I carry everywhere, I live in the country and have dangerous animals around me, even without the human ones. I have used a firearm to convince stupid people to pick a different would-be victim and would do it again, what the law says about it, well I will worry about that later, if it's needed.
What I will not do is defend someone I do not know and care about. I would make an allowance at church or somewhere my own friends and family were at. I decided long ago if someone is dealing with a lefty, it is not my problem. I will not help, record it (not a witness) or interfere. After years of hearing them screaming about my side being their sword enemy, I believe them.
They are on their own, no help coming. It doesn't matter what kind of help they need. I am not alone in this either. Look at the difference in the responses to the NC floods and the Cal fires, no one cared about Cal, still don't.
