I am going to take your deflective answer as: no you wouldn't be more inclined to commit mass murder if you owned an AR. So the obvious follow-up question to that is (which I'm sure you have been avoiding because you knew where I was going with this)... What makes you think the 99.9% of American would suddenly become more inclined to commit any sort of murder if they owned an 'assault rifle'? The vast majority of gun owners are just like you, responsible Americans with absolutely no intention to harm any innocent person regardless of what weapon they won. I would not more commit murder if I had a RPG than I would if I had a bb gun. Law-respecting Americans, that have done some study of the constitution, know the danger of having a government that can disarm us. The French are virtually completely disarmed, and yet terrorists managed to get automatic weapons into that country and commit mass murder. Brits are banned from having bombs, but terrorists managed to get bombs into the country and kill 22 people.
I'm at a point where I almost welcome you libs getting your way and banning guns and see the results. Then call for more bans, only to learn that it doesn't prevent these killings. Your answer to every problem is to have the government come in and limit innocent Americans' lives to answer for an extreme few nut cases. And when you've managed to ban every firearm, we'll still have nut cases that will get their hands on weapons to kill in mass numbers.
