Why are kpop stans of afro-descent so heavily shamed??

kpop really opened my eyes. Im african american and honestly IM so glad i dont listen to some of these rappers. But why are kpop stans of afro-descent so heavily shamed by others of afro-descent. Even by my family, i dont understand it. Im honestly scared to ask my family why. I tried once and my dad said it was bcs it was different, but my cousin watches telanovelas all day and nobody cares. Why is it just kpop?
