@Whiskey:
1. - a/b/c : So basically, they bark at mostly everything
You are pretty much repeating what I said. Dogs bark ALL the time. (I trust that you didnt take "all the time" part literally, of course.)
2. They crap anyplace they want, UNLESS you train them. Besides, like I already said, you have to take them for a walk in the park or something, and even so, they will take a dump almost anywhere, so good luck teaching your dog where exactly do you allow them to take a dump, outdoors. In other words, you have to teach your dog not to crap inside your house, and then you have to teach them where to take a dump outside the house, which is even more difficult. Good luck with all that 
3. No, they just require so much from you, and they take too much of your spare time. If you want to devote yourself to your pet, to the point that the dog is almost like family, then yeah, look no further: dogs are the way to go, if you are that way. Cats require so little from you, and are almost never a nuisance.
4. Exactly. You have to train them not to do "bad things", and thats never too easy. A cat wont break too many things in your house, it wont jump on unsuspected visitors, it wont bite passerby's, etc etc. Do you want me to go on?
5. Yeah, you might have some well-trained, well behaved dogs. But that doesnt change the fact that cats are quiet, calm, and generally well behaved animals 99% of the time, while dogs are ill behaved and "naughty" 90% of the time. If you bought your dog from a store where they train it, then good for you. If you took a stray dog, and trained it yourself, then you can understand what I'm talking about here.
About Cats:
1. First of all, cats dont carry as much diseases as other animals. That said, if you care for your cat, then taking it to the vet for some vaccinations is never a bad thing. Besides, I have had more than 50 cats in my 22 years of life. I never ever contracted any diseases from my cats. My mother once told me, that I would pet the cat we owned, at the age of 3, and all cats we had when I was a kid/baby we had them taken to the vet for vaccines regularly, because my parents didnt want their baby to contract any diseases. If you let your kid play with any pets like cats and dogs, and you dont have them taken to the vet, then you are really asking for it. Finally, both cats and dogs can carry diseases, and judging from the fact that dogs are generally bigger (depending on the dog's race of course), I'd say that dogs may carry more diseases than cats, although honestly, I'd put them on same ground here. To answer directly to your argument, just take your cat to the vet, and/or have it live inside your house.
2. I dont see what your argument has to do with what I said, but:
a. The chances of finding a stray cat, that could have some kind of disease and take it as your pet, are no more and no less than the chances of finding a stray dog that could have some kind of disease.
b. This isnt really an argument. Most animals similar to cats/dogs can carry diseases that can be contracted by humans. Finding a stray animal and taking it as your pet, and then finding out that it carries some sort of disease, is always a possibility. If you want to be "safe", then buy a cat/ dog from a store, or just take your ex-wild cat/dog to the vet for vaccines. Its really your choice.
c. Wild cats are aggressive? Thats why I love them!
Because it takes effort to tame a wild cat, to make it trust you and eventually let you pet it. And for the last time, this IS NOT an argument Whiskey
If you dont like wild animals, which are 99% more aggressive than animals sold at pet shops, then dont freaking get a wild one. FYI, try messing with a big wild dog, and try messing with a wild cat. The wild cat will give you some mild scratches at best (they mostly run with fear from humans, but ok, whatever), while the wild dog will give you some nice bites, or even send you straight to the hospital, if its a really aggressive and badass kind of dog.
3. Not really, dogs are either retarded looking animals with their tongue sticking out, being all like: "Woof, woof, I love you, plz play with meh! Look, I drool all over your couch!! ISNT THAT CUTE?!?" OR they are aggressive savage beasts, that will bark and bite anything passing anywhere near them, being all like: "I AM GONNA KILL YOU NAO!! RAWRRRR"
4. Uh, EXCUSE ME?
Do you have a a litter box for your dog? No? I didnt think so, because if the dog poops in a huge litter box inside your house, your are probably gonna die from the stench, while the cat is more discrete and doesnt poop so much. If that is your argument, then let me tell you that you take your dog outside to take a dump, and it craps anywhere it wants, usually, leaving a pile of sh!t somewhere, while the cat WILL burry their feces on soil 99% of the time. Which is better? 
If you dont want your pet crapping inside your house, then just take it outside to do it. You dont need to be so smart to figure it out. The thing is, that with cats, at least you have the option of having a litter box for it, and it can do whatever it needs to do in there. While with dogs, having a litter box for it.......is not really an option.... 
Come on Whiskey, you're smart. Dont act stupid on me now.
5. Thats the lamest, most ridiculous, most idiotic argument I have ever heard on a dogs vs cats debate. Honestly, did you seriously say that as an argument?
Really? 
ROFLMAO!
6. The usual eternal argument of dog lovers. "Dogs are good guardians. They will protect you." Let me say something. If you want protection, then get a freaking gun. Having your pet as a bodyguard, and say, "look, if you kick me, he will bite you, he's so loyal and protective. I love this dog!", is just plain stupid. Let me tell you something else. Dogs are stupid. Some ill behaved dogs will attack a friend or relative visiting, and random people walking on the street. Some dogs have real trouble recognizing what people are part of the pack, and which arent. In short, they cant really distinguish when there's a threat and they should attack, and when there's nothing wrong. Moreover, if you get mugged on the street, from a guy pointing a gun at you, having your dog with you wont help you. AT ALL. I dont think a serious criminal pointing a gun at a human, will have trouble shooting your dog on sight, if they consider your dog to be a threat to their mugging you, so basically, you better NOT have your dog with you, unless you want a high chance of it being murdered by a criminal. Besides, even if you have your dog with you while someone attempts to mug you, do you REALLY think that the dog will understand there's some kind of danger, and attack? The mugger probably wont YELL "GIVE ME ALL YOUR CASH OR I AM GONNA KILL YOU!", yeah that wont bring the cops around. The mugger will probably be smart about this, (unless they suck, in which case a cop might appear, if you're lucky), and be intimidating, and discrete at the same time. Lastly, if your dog is like PRO bodyguard and senses danger from miles away (trained as a police dog), then you REALLY dont want it to attack the mugger. I know I wouldnt want my dog to die protecting my wallet, and I certainly dont want to die because of it.
Taking the mugging scenario aside, on a life/death situation, where you have no other means of protecting yourself, and you think "I am so freaking dead. I better pray now", then yes a dog might actually save your life, even if it dies for it. But these situations are extremely rare and even so, I would STILL prefer a gun from a dog any time of the day. The dog might try to protect me in this extreme situation, it doesnt mean it can succeed though. The chances of your dog actually saving your life are nearly 0, while if you were dumb enough to go into trouble, and find yourself having a bounty on your head, then you suck, LOL.
If someone wants to rob my house, and I have no means of protecting myself (no guns, no dial-police-button hidden in the wall or something), which is just dumb btw, you should always have a means of protecting yourself, your family and your home, anyway, if there is no other way, then I wouldnt want my dog attacking the armed robber, because if it does, then it might die for it, or even worse I might die for it. In that case, which I have no means of protecting my property, then I will let the robber(s) take anything they want. I dont think its worth risking my life when I have less than 10% chances of driving away armed robbers, because I was dumb enough not to have a gun or something.
Lastly, if I wanted to break into a house, and rob it, I would first consider every possible scenario, like the one that I get attacked by a big nasty "OMGWTF I am gonna kill you" kind of dog, and equip myself with a nice poisoned but tasty steak. Your guardian-dog IS going to love that steak, before it drops dead to the ground. If someone is dumb enough to go rob a house, ignoring the big dog, then they suck, LOL.
In short, these situations are really rare, and you have to protect yourself 99% of the time (or just being protected by a close relative or friend, or something), the dog may save your life only on some very rare situations, where lots of luck is involved.
7. Not just that, there are tons of good qualities that cats possess, and very few flaws, while the opposite applies for dogs. I admit that dogs can have a few qualities though, even though their flaws overlap these qualities.
Dont bring the "guardian" argument over and over again. We get it. You trust your dog with your life. Foolish, but its your choice.
To summarize, cats are a lot more discrete, quiet, calm animals, while dogs are usually a lot more aggressive, noisy, dirty and naughty. Cats dont require as much affection and caring as dogs do, they wont complain intensely if you dont feed them and can feed on their own, in opposite to dogs who cant really feed on their own if needed be.
I have had more than 50+ cats in my 22 years of life, and 17 dogs (I know the number of dogs is much smaller, but not too much), and I can honestly say, that I prefer having a cat than having a dog as a pet, by far. (The list also includes many other animals, from fish and turtles, to spiders and snakes, but thats another story)
My last argument, (which isnt really an argument), I think cats are extremely kewt, while dogs are not as much. Cats rule, dogs suck.
