I believe the phrase let people enjoy things applies here
But on your point, what's wrong with me wanting to be black and NOT American?
Many young are impressionable yes, but also many find an identity they like, for example I wear skateboard shoes exclusively which are considered bad taste at any formal occasion, but they are from my roots and that's how I roll and frankly why the fuck would my footwear affect your life in terms of simple physics.. it's doesn't
Classic case of making something out of nothing, people are bored I guess
