I can enjoy fictional 'anime-rape' and still talk about serious rape as part of a serious story. If you want to make this about me, I'd tell you that rape-fantasies are the absolute #1 on any hentai-website, meaning it's neither rare nor fringe to enjoy that type of scenes. Ofc we live in a society that is still very puritan in terms of sex, so most people wouldn't publically admit to liking these doujins - since I want to live in a world where creatice freedom reigns supreme, however, I do.
But again, now we're talking about h-content meant to arouse. Any debate about rape in GS or other serious anime has completely different connotations. It's not there to arouse. Ofc, due to the character design and the shown face during the rape, GS's rape walks a thin line. Really, you could argue either way. My stance: actual rape victims experience orgasm, too, so it's fair to show a moaning face in GS. But since rape is such a rare occurrence in fictional media, it's unfortunate that the one time we get rape (which we should have more of, in relation to all the killing) it's kind of sexy in how it's presented.
Edit: Wow, you guys really keep giving me these new page-top-postings xD
