“X for black people” sounds so bizarre to me(non-American). The cultural divide between the people must be insane.
Is more or less what I thought, (with the difference that I thought "Y for Z people").
So I can't judge if it's necessary or makes sense, but from the point of the author it seems to be the case.
Which is sad as black people are not a small minority in the US and so I would expect more representation of them.
I mean Netflix (or any thing similar) should be "for everyone" featuring a diverse mix at least similar to reality (or maybe slightly more diverse (1) ).
(1): For minorities in a country representation with a mix "like reality" would mean they would not get much representation as just a number of content thingies would represent them. So increasing the degree of diversity above it is I think a good idea.
