Russia, Brazil, and Mexico have much stricter firearms regulation than the US and yet have higher percapita firearms death rates; additionally, Switzerland has more liberal firearms regulation and a lower rate than the US.

The data doesn't lie. There is a serious implication that more privately held firearms will yeild lower homicide rates as a whole.

Why is he being labeled a troll?

Because since he signed up on GC he has just pulled up old threads and made inflammatory comments.

How is expressing a simple opinion, in a non-threatening manner, inflammatory? Just because your opinion differs from someone else's, does not mean that a person is trying to irritate you; rather, you have an opportunity to offer your opinion while supporting it with valid and legitimate arguments. Truthfully, this sort of knee-jerk reaction is far more common than it should be.

He's not a troll. As for pulling up old threads, who cares? It's not like a hell of a lot else is happening on here.
