Not to extinguish the flames of racial hatred, but the last movie I went to which was Avengers 3, it was 4 drunk white kids who were being annoying. I could have whipped their asses (not trying to be tuff, but they were small and drunk), but instead I got up and told an usher. I'm not even trying g to have to diplomatically talk to some asshole about how they need to shut up, because it will only cause problems, and in most situations, I'm the one with more to lose.
I will say though, that if someone gets one their phone, black white drunk or whatever, I usually say something about that.
