Perhaps, but if so, it only appears that way because gun owners have been silent and civilized about the thing. We are not in a minority on the issue, as is evidenced every time this issue comes up on the ballot as well as by recent polls concerning gun control. Gun control proponents have always been in the minority; a noisy, well-organize minority, yes, and now with media help they can appear as a majority.
I used to be against this sort of behavior because I felt that the reality of gun ownership by calm, normal people was the image that was important to present. I believe now that it is important to present an outraged image for precisely the reason you articulated above: we look like we're a quiet, cooperative minority. We need to be loud, passionate, in-your-face because that's the coin of the political realm at the moment. Not irresponsible or reckless, but I'm thinking anger is no longer out of bounds. IMHO, of course.
I don’t think it just appears that way, look who got elected. I have never had anything about gun control on any ballot I’ve seen.
