No one seems to take hentai seriously, at least in the West. To them it's just "Ooooh I love those crazy, perverted Japanese!" I don't understand how stuff like hentai and adult film can be looked down upon (and I would tend to agree with that) and yet at the same time be so heavily marketed and consumed by both Japanese and foreign audiences. People say Japan is so open and tolerant of even the most egregious things. Really? I find it rather hard to believe the average Japanese wouldn't have a problem with at least one of these things, despite what the media and Internet portray.
