Where did you see people of all races coming together? Maybe it's just because I'm from the Deep South, but I was raised to be racist. Racism was a normal part of life for me, I wasn't even allowed in the same water as negros at the beach when I was a kid. My grandparents restaurant was Whites Only before that became illegal, but my the only ones who ever went in there was the negros my grandpa hired to work in the kitchen, other than that they stayed away. They couldn't afford it anyways.
Point is, this whole anti-racist shit has always been the dregs of society lashing out that they're the dregs, and they just need to be reminded of that and given a hard look in the mirror if you ask me.
