Already a thread about it.
I don't see why you need to bash people who like Hentai. What's wrong with it? You yourself might like (regular) straight porn, or gay porn, if you're gay, or whatever (not implying that you are, only saying it 'just in case'馃槈. Or maybe you don't like any kind of porn, but assuming you do, would you like it if people started making fun of your interests and insulting you about it? If people like hentai, let them be. If people like regular porn, let them be. It's their choice to watch it, not yours. If you don't like it, leave it alone, no one's forcing you to watch it.
