Should Straight people not read yaoi ?

Their are people on twitter who say yaoi is fetishizing of gay couples ..
I been reading yaoi for long time and I have never disrespect or fetishize any gay people in real life , I may have ship some kpop idols or anime characters but everyone else did it .. to me I like yaoi and I don't even know why it just make me happy when I read it .. so what wrong with that ?

Why can't straight girls like and read yaoi ? How should I respond to those accusations made by those people ?
