One advantage of being an alien resident in the US, as far as I'm concerned, is that I can't own firearms. Never wanted to, can't see any good reason for carrying a device that would enable me to end another person's life. Maybe that's a throwback to being British, where, in general when we lived there, the only guns that could be privately owned were shotguns owned by farmers.
I'm aware that a lot of NRA members would think I'm a Commie-loving wimp, but that's my opinion, and I don'r give a rat's what those loonies think.
