Why do straight guys hate female pop artists?

ok so I'm gay..but not flaming gay.. but i still like mainstream pop music just like a lot of people do. But why is it that I run into many straight guys that "hate" them.. some examples would be rihanna, christina, kelly clarkson, beyonce..etc... whats the problem? Is it a pride thing? Are you guys afraid of admitting you like them? Be honest!!! I wanna hear from straight guys!!!!
