Why are K-pop fans being inconsiderate towards gay idols?

Let's face the truth, how is it even possible that there isn't even one same-sex couple in 370 K-pop groups? What are the odds? It's so childish to always create a paradoxical world around them and throw the burden of this absurd fantasy onto the idols. Just because a gay idol might not fit the nonsensical world, they are boycotted and separated from their dream. Well that's immoral. Just enjoy the music, choreography and hard work behind all of it! Why is the idea of a gay idol so repelling?
