It isn't only in yaoi o bl manga in general, in most of the shoujo manga that I've read so far the bitches are women and always they've been rejected by the male protagonist, just because they think they're the best... Well in real life too I think that these types of people, male or famale, are by nature asshole , so in yaoi manga case (or real life too) this is exasperated precisely because women know that they have a trump card more than men ( ̄へ ̄)

I don't think this is the case? This types of Women, who are on this Manga, are pretty much harmless in comparison to other I have meet in RL or in other yaoi manga, I'm a woman but I don't feel that they have disrespected me in any way, in my country I have another way of thinking, Japanese have they're and except for a few extreme Manga and some unrealistic ones , we are talking about how the mangakas in most yaoi manga shows the reality of gay in Japan, so if most of the time women are portrayed in that way maybe it's true? I don't know exactly if it's true or not, but in this case, maybe, I think Japanese women are the one who most likely have to feel offended? In what country real life are you talking about, it's the other way around? Maybe in your country, but I'm sorry to say this In my country the women are the most hassoles in both case.
Maybe I’m over thinking but why in yaoi mangas always most of bitches and the ppl who get rejected are women?
