There is no way I could do your job, brother. I applaud you for having to deal with drunken ignorant people whatever race they are, and with the regularity that you describe.

I would hedge a bet on the "you owe me" mentality that some Americans harbor. While I believe there is blatant idiocy within all races and "classes". At a significant level, I'm not at all surprised to hear that who you described was acting the way they were acting. Assaulting the old man on the way out the door is appalling and inexcusable. I'm guessing the guard was white?

I believe many BLM champions are idiots with limited education riding a wave of misplaced emotion and rhetoric. Poor cultural behavior breeds further poor behavior among any circle of ethnicity.
