Horrible situation, but honestly some of this is needed for dumb white people. The woman didn't deserve to be beat for trying to stop it though.
I'm white, none of us know all the details of this case, but the amount of videos I've seen of racist white people thinking they can say or do whatever is absolutely insane. There's a famous video depicting almost this exact situation: Drunk as fuck middle aged white guy and wife, in Thailand, talking shit about the country and the people and how America is so much better. And guess what? The crowd beat the fuck out of them and left them unconscious in the street.
That's what's needed for some hateful people, to get that same hate back. Then maybe they'll change their idiotic behaviors and opinions.
Also, make a thread for every racist attack on black/latin/asian people and I'm sure you'll have 1000x more threads than one of these.
