So MMM troll person... whats to stop me, post utopian gun eradication, from walking up to your kids in your front yard and gutting them like fish? Then we'll ban knives, right? Hey, that sounds like England! Then we'll need to be 18+ to buy butter knives and forks. And then screwdrivers (much worse than knives). Then maybe we should restrict / ban pencils and pens!
OH! Maybe we should ban the most dangerous item you have! Your car! Id be willing to bet, not counting all those who die in true accidents, that more people are killed by vehicles being used intentionally as weapons than those who die by firearm / knife in our society. (not including hellholes like Africa)
What then? I still have the most deadly weapon on the planet. My body. More people are killed by straight beatings than anything else. Period. So then we'll remove our hands / feet, right?
But wait! If you had a firearm, you could stop me from beating you senseless in your own home! Ah... the circle of life. (or death)
