Don't be sarcastic

I would say that if you know that there is no way rape is okay irl and you're not romanticizing it, it's fine. But it's not the case for everyone that's why people are sensitive about this issue.
Many people are not able to recognize rape and say (or think) dumb statements like "they had an orgasm so it's not rape", "he put his dick between their legs and not inside so it's not rape", "they're dating so it's not rape"... In that case, seeing rape in stories will confort them in that way of thinking even more because most of the stories are supposed to reflect reality.

I think that liking rape in fiction is okay but you have to educate people on:
- what is rape
- the difference between fiction and reality
- why is it not okay irl
If you're okay on these matters, it's fine. Unfortunately, many people are not. I saw that there is a Mangago Highschool maybe that could be an occasion to teach something useful haha
