If the anti gun know it all's are serious about understanding how the real world works. I would strongly encourage watching Underworld Inc on netflix. Episode 1. Ghost guns.
The extremes accomplish nothing. America should adopt and enforce strict laws about education and training for firearms before ownership. Banning them will do literally nothing. Banning may work in some cultures and not in others. It's not going to work in america. Watch the show!!
The folks like fink who spout nonsensical information that reveal their ignorance of the matter are undermining a discussion about doing something that could actually improve things. See I'm not debating for either extreme pro gun nut or anti gun nut so don't say how I'm not debating well. I'm not debating at all. Just calling BS when I see it.
Watch the episode and get back to me :)
