I agree. The fanbase of Yaoi is largely women so any fantasizes and sexual tensions that can be appealing will be represented in these kinds of comics. Like any sexual fantasy, (some can't seem to acknowledge that Yaoi is a kind of porn,) so yes, rape tropes will be in some of them like cosplay or whatever. I could not care whether or not the story has rape because if you are reading Yaoi hopefully you are not only mature enough to differentiate fantasy and fiction but hopefully sensible enough to know that there is a wide array to suit people of all tastes and it's rude to try to "correct" their taste by pushing your own onto them. I get rather annoyed when people are quick to complain "oh this story has rape in it, burn the thing I hated it, it's not suitable for society" or wish the story to represent reality and get livid when there's a dramatic antagonist implied in the story. Depending on the mood I can find those kinds of stories interesting or sexy and there's nothing wrong with that. Let them have their opinions but to me it just comes off as though someone who hasn't had proper sex ed is trying to stand on a soap box. Sincerely, if this was the only way a person knew about sex, via Yaoi/internet, relationships in the real world will become a bit shocking.
Too those people, I say: of course rape is bad!! But they need to draw the line from FICTION and REALITY!!! It's like with shota and incest. We all like it in fiction 'cause of our inner sadist/masochist (we all have them >:D), we sometimes want some more intensity. But if we hear about that in real life, we would all be horrified and wish the assaulter to be tortured painfully.
Oh, but I don't like when the story's just all about rape and no plot, I like consensual PWP. :b
tl;dr: I agree with you, Toad, Anon, and Bad-Girl. (=・ω・=)
Yaoi manga with rape, people is like: "I hate rape!!!" "Warning:rape"
Me: i dont care if there is rape or not as long as it is interesting. ╮( ̄▽ ̄)╭
I think seeing rape can be interesting since the sex is much more intense. No wait, rape with feelings for the victim is even more intense and much better. (My opinion. Don't hate me for my opinion.) I am a sadist. I like seeing people suffer.... Is that bad......? Σ(  ̄□ ̄||) .... nah i am proud of who I am on the inside. (=・ω・=)
