It's really comforting to know I'm sharing a society with you people. (and no, I wouldn't dare say something like that to someone with a knife if there weren't a wall of cyberspace anonymity between us.)
But I'm probably not going to stay indoors. I'd prefer to bank on my diplomacy, and I think being unarmed gives people a better impression of my intentions. If I can't run away or talk my way out of a situation, I'd rather just go ahead and die than live with someone else's blood on my hands.
I'm depressed that our society has degenerated to the point that people have to arm themselves to avoid dying in the typical public place.
