serious question

i hate how ppl attack artists for not posting something for pride month or mentioning pride month but when its february everybody is silent. whys it okay to ignore black history month but such a disgusting thing to ignore pride month? and people like to say "its because im not black so i cant relate to celebrating black history month". ok and the artist is straight so they cant relate to pride month, keep the same energy. it doesn't make sense to me how one is okay and the other isn't. I've seen countless artists get dragged, harassed, and called homophobic for not posting but nobody calls them racist for not posting for black history month(i dont think its racist im using racist to compare to homophobic). can somebody give me a serious answer please
