I don't like the behavior, I would not want my children to emulate them - which of would really not be a problem for any decent parent.   But I don't know their story, I don't know how they got to that point, I can't say I wouldn't have done the same thing in the same circumstances.     They are still people.  

I'm trying to leave my Christian thinking out it, but it does shape this response.   I can leave out the religious words but that doesn't change the impact of compassion and forgiveness, on my thinking.    I have no illusions that I live up to the ideal. 

*I'm not a fool either, I don't spend time hanging out in the square, and the temper tantrums are common.   It's a personal choice to avoid groups that are 'edgy'.    Self preservation instinct.   I wouldn't walk into a group of angry NRA protestors either.   Neither probably a big risk, but why test the theory!
