Yeah, violence -or the discussion thereof- is definitely the way to get you noticed and have your opinion heard.
As a more constructive comment: Try writing (or emailing) your representatives about the issue. True, your one voice won't mean much, but other people are writing. You honestly don't know which letter will push them far enough to take this seriously.
In addition, do your best to ensure you discuss the topic calmly and intelligently. The people who talk using internet slang or threats are stereotypically the non-voting populace, and they are thus often ignored by the people whose primary concern is getting votes.
