Besides that, what is wrong with “black face” portrayals of black people? What would’ve been racist is to portray black people as white people. Explain to me why it isn't "racist" when African-American women apply skin "whiteners", pour peroxide on their hair, and drench it in "straighteners".
Amazing, isn't it? The absurdity started when panderers and PC maniacs let blacks own the language and the culture. They can use the "n" word; we can't. Black Lives Matter. Blacks are under-represented in some entertainment spheres (no more) but whites can be under-represented in the NBA or for college athletic scholarships. Black and Native portrayals are racist when they're portrayed; racist when they're ignored. A black committing a crime against a white isn't a hate crime. We can't honor any historical figure who was racist by today's standards. And the thought police get to say what's in someone's heart and mind.
It's a destruction of our freedoms and cultures. I keep saying it. Civilization as we used to know it isn't just on its way out; we're way down that slippery slope toward as Sci-Fi like totalitarian post-human world. Folks letting it happen think it's just fine.
