Hmm. Interesting question.
I'm assuming you're referring to the whole issue with tentacles and furies. To this very point, I will point out the existence of Rape, Beastiality, Incest, Pedophilia, and a whole range more of pornographic genres which exist on this very internet. If I asked you whether any of them were bad, chances are you would say yes. If not, I'm a tiny bit worried.
But what if I asked you whether you thought porn in general was bad? 83%Probably higher than this, but I couldn't resist the reference of people on this forum would say that it most certainly isn't. They're two completely different questions. So, I believe that Hentai is good. At least, it isn't bad. I'm honestly not that interested in porn and the like, but as far as it goes, Hentai is just as good as normal porn in my mind. As to your other, unasked question: personally, I don't like tentacle and furies, however, I acknowledge that some people do, and respect their opinions.
As to the point that Hentai also includes Rape, Beastiality, etc etc, I agree, yes, it does. However, these acts are completely taboo, and I think that if these videos must exist, better they be animation than a recording of the real thing; because in one, the act isn't committed.
