I was raised with guns in the house. I knew where they were, and I knew what they could do. When you see a .357 magnum atomize most of a cinder block around age five, you get the picture: these things are not toys. I got my first gun when I turned ten years old, a double barrel .410. After a couple months, I switched to the 12 gauge because the .410 shells were ridiculously overpriced in that market. Learning to shoot was an important rite of passage in my family, and I've passed it on, despite having no kids of my own yet: I taught a friend's son how to shoot.
Sure, I get angry sometimes. There are days I wouldn't mind liquidating entire departments when I'm in a bad mood, but I don't do it. I was raised properly. No amount of violent video games, television, cinema, music or literature is going to flip a switch and make me think it is a good idea to go on a lead and cordite rampage. When I hear about a teenager going on a shooting spree, my first thought isn't "oh no, they gonna wanna take my-ah guns" or "wow, somebody should really take all the guns" it is "Bad parenting."
Actually, if I were to go on a rampage, I'd probably use a Prius or something, just to give Prius owners the same kind of black eye that gun owners have been getting in the media.
Where do you draw the line? We've hit a point where people kill themselves over internet bullying.
Treat the cause, not the symptom.
