..a study that has any of the meaning behind the word isn't for you to "believe" in. It's fact. Only 1 of the studies with opposing viewpoints is valid, and I'd be willing to bet everything I own that you are on the wrong side. But of course, guns and your need to have the biggest most deadly ones borders on religion in the US. I don't expect you to be reasonable, so do us all a favour and stop pretending you are.
Maybe if you live in Baghdad, suburban US? Not so much. It's the number 1 choice of mass murderers. MAYBE you should do some long hard thinking.
