Fair point. How about "Rap for white people" - a record label that only features white rappers for people that want to hear more suburban white-America culture expressed through rap? Still might ignite a firestorm, all it takes is one media outlet framing it as racist.

It might ignite a firestorm but this might too on more right wing channels (e.g. Breitbart), it's just that those channels aren't as represented in "mainstream" media

You deny reality --"White and black basketball players aren't different physically" seriously? The only reason blacks dominate bball is bc they are different physically. The same for why we have women's sports that exclude men. The reason why blacks need to create X for blacks is often because they can't compete without it, which just means yes groups on avg are different. Whites can't compete with black bball players. Groups on average are different. So yes, I can see why there is a reason and market for a NBA for whites.
