Random thought ... if appreciating music styles that to some degree originated among blacks is "cultural appropriation", were "white" Motown fans cultural-appropriators? People who love the music of Duke Ellington and Count Basie? Chubby Checker, Little Richard, and Chuck Berry?
OTOH, sports like basketball, football, and baseball were created by "whites" ...
At the risk of committing cultural appropriation, How Low Can Stupid Go?!
