I misread the post. I thought it said "shooting folks you don't know" so I was about to say, what's wrong with that? That's what we do in combat, and under the right circumstances, it is unambiguous so we know who to shoot at. To shoot WITH strangers, I would just as soon avoid it not knowing who is going to put me in danger through stupid behavior.
