You like Yaoi? Then, it's good for you!
But harassing people because they don't like it, or because they just don't give a shit about it, is freaking stupid.
Yeah, Yaoi is popular. It doesn't mean it's wonderful, and it doesn't mean that EVERYBODY has to love it!
People are free to dislike it, don't call them "HATERS" (or even more stupid, "homophobes") just because they don't like your favourite fandom.
