There may be people who say that banning certain types of guns will solve the problem, or just solve a problem. You can argue with them, because I'm not one of those people. I believe that we have a huge, complicated problem with gun violence in this country and it has to do with a lot of things - the media, our treatment of mental health issues, health care in general, economic disparity, the existence of sociopaths, and the unknown. And the gun culture we have doesn't help. A lot of Americans are so afraid that they're going to be attacked by a group of gang members who want nothing more than to kill a random person. That's paranoid and delusional thinking which has no basis on reality.
My argument is pretty simple. If you were going to kill a lot of people, do you think you would want to use handguns or a bush master? Or if your family was being attacked by a hundred mafia members with tommy guns, which gun would you choose?
The latter doesn't ever happen, but the former does. That's it. Common sense. You're arguing as though I'm proposing that banning certain types of guns will solve a problem, and my argument is that it could prevent a horrible, horrible tragedy - or rather, it could change a horrible, horrible tragedy into a horrible tragedy.
