Thoughts about rape in fiction?

Its here. We need to talk about this. I personally don't get why's people being mad about rape in mangas, manhwas, fanfics, etc. I mean sure its okay to have opinions. But sometimes, i saw some people commenting, saying how they dont support rape etc, even blaming the manga-- Even when the translator literally put a warning.
Me personally, it doesn't bother me a lot since i know the difference between fantasy and reality. But i want to know other people's thoughts too.
