Totally agree with you!
It's so hard to put into words!
But your equation pretty much describes my feelings on it:
Rape = just a normal way to get someone to like you. and for some reason it's not a big deal
no
Rape = messed up, forceful thing that makes you aware that what's happening is not ok, but it actually helps with plot development or creates a dynamic and different kind of story
yes (but only in a freaking story)
I'm not completely averse to rape as long as it doesn't glorify it. This oneshot is psychological, the character is disturbed; you're not supposed to agree with his actions. It's those mangas which have the theme of "YOUR MOUTH IS SAYING NO BUT YOUR BODY IS SAYING YES ;]" and somehow readers think it's super romantic which really leave a bad taste in my mouth.
Characters who have a fucked up relationship and the reader is supposed to acknowledge that it is fucked up = okay in my book.
Characters who have a fucked up relationship that is supposed to be adorable/sexy = not okay. I don't like reading those ones; and I also think it's just a really shitty, overused trope in yaoi. I can't think of one manga that does this that I've enjoyed.
