I don’t like being called whitewashed

Why is it that if I like something I get called whitewashed for liking it like if I like a certain style I’m called “white” or if I talk “proper” I get called white like how is a black person supposed to talk I can’t even dress how I want cus ppl always say it’s a “white person style “ it’s so annoying and I should be able to like what I like without being judged for it
