Blaming white people for something that has been around since the dawn of time, since before there were white people, black people or Asians does nothing except make sure that social division lines remain fully in place... Constantly reminding peope of a certain culture that people from the next culture fucked them over means that there will always be the two cultures at odds with eachother, instead of moving forward and coexisting without the past dragging us back into the mud.
The last 20 years have seen society move in a very negative way - back in the 90s there was a real feeling that people were coming together - these days we couldn't be further apart, and in my opinion it's the constant "400 years of hurt" shit that has been coming out of the woodwork.
Also the rise of the cuckold has added a sexual element to the situation that sees certain women racially dismissing their own race, and another group doing it to as a way of repatriation. Of course people are getting bent out of shape. It's getting to the point where everything is a race issue.
The ghost busters reboot is a prime example. Take Winston Zedmore - back in the mid 80s Winston was just another guy looking for a job. He turned up, he put in his shift, he was one of the guys, and nobody mention the fact he was back single time... Fast forward to 2016 and what does the one black character do...? Puts rims and a boom box onto Ecto-1 and spends the whole movie talking in stereotypical "urban slang" with one hand up... It was like a fucking Minstrel show. Applling.
My point is that the more you point out how people are different, the more problems arise. I'm not saying that things were great back in the 80s at all, but at least it felt like things were moving forward... Socially I think we peaked in the 90s. It's all been downhill since then.
I'm no racist, despite taking a hardline on a lot of the hard left's limp wristed caterwauling - I hate that shit just as much as I hate the hard right's hateful agenda... They'e both as bad as soon eachother and create problems that don't exist... People are people, it' in our nature to look for differences - the more people point out issues, and use differences as a weapon of manipulation rather than a celebration of diversity the more shit festers.
Does that all make sense or am I just rambling?
