Ever heard of black girls rock? This is a meme but most people have no clue.
> It's encouraging race discrimination either way
WHO is encouraged to discriminate racially by this? You? Not me.
If you are concerned with racial discrimination, please go visit your public schools across whatever U.S. state you live in and try to explain why there is such racial segregation even in the absence of school names such as Black Boys Academy. Hint, it ain't in the name.
They are, by their own name, discriminating based on race. Even if it is for a positive goal. The problem is that it reinforces race as a significant distinguishing category when it should not be. Many other categories are far more significant. Like income level. In general, a very poor black girl and very poor white girl will have much more in common than a very poor black girl and a very rich black girl.
