Rape

Why is Rape romanticized so much in manga, especially the Japanese ones. I am not okay with rape, like at all. If I hear about it, or encounter someone who has been raped, my blood boil for the victims. Also, I get so mad when I hear about the statistic of the molesters that get away with it . Yet, when I read it in manga, I don't exactly care. I'm not sure why? I thought that maybe I had a rape fetch, so I subscribed to this website (pornographic) and watched a video about that, but couldn't even get to the half of it, and I almost threw my phone out of the window.
My friend think it's because manga romanticize Rape a lot. So, my brain learned the pattern and now, when I see Rape in manga, I automatically just assume it's gonna have a "happy ending."
OR maybe it's because I know they're not real people.
OR maybe it's like Bill Burr said: no body care about cartoon kids. You can yell, insult and even scream at children in cartoon, but it'd be a different story with real kids. (You know with children being victims in this analogy)
I honestly don't know anymore, and usually I feel really bad after I read a story like this. So, I tried to avoid them. But it's kinda hard, because every other manga is Rape-based. It's frustrating.
