If you believe that there are laws that actually prevent crooks from getting guns then you're extremely gullible, And if you believe that we should have such laws, then by my definition you ARE anti-gun and I don't give a rat's ass about your NRA membership.
Do you believe violently crazy people should have gun rights? Like that kook who shot Gabriel what's her name. Everyone knew he was nuts, no way should he have the ability to get a gun. Yes, you can't prevent criminals from getting guns but if legal guns are easy to get, there would have been several armed folks to bring him down before he got more than a shot or two off.
