While I don't think these polls really mean anything (because I know I voted twice!), and I certainly don't think they can be used to prove anything, I think that the results are informative in an anecdotal way. If we assume an equal level of response and honesty across the playing field (a truly specious assumption), then nearly half of the population here genuinely thinks increased gun ownership is a bad idea. By extension, they must think that gun ownership is a bad idea period.
This isn't something to poo-pooh, or dismiss, or complain about. it is something to be alarmed by. This is the reason that the few genuine antis out there have the ability to make such an impact.
I think that, by and large, this feeling isn't wrong, and it isn't a conscious choice of "guns are bad" that has been made. It is simple ignorance.
Ignorance is the enemy, not the antis. The antis have made a philosophical choice, and they are pursuing it zealously, as is their right. It is only because their support base is largely ignorant of the matter that the anti-influence has any power at all. So, rather than fighting the antis (which is a zero sum endgame proposition), we need instead to focus our energies on educating the masses.
This is true of pretty much any issue you care to name... abortion, health care, the war in Iraq, nuclear waste, prayer in public schools, gay marriage, etc. One way to start a war is to start slinging propaganda. This will have the guaranteed effect of creating an opposition and launching a perpetual feud. We've tried that, and are still trying that, with predictable results.
Maybe it's time to try something new...
