Eh like me and Steamboat said this isn't new.The shitstorm over Interspecies Reviewers is worrying, I sure hope Japan doesn't get a bug up it's ass about sexual content like the west has.
But Japan has always had a diehard conservative element, we are talking a country that censors genitals in porn as if that makes any sense or the country that has over 9000 porn video games but mainstream games with CERO ratings don't allow topless women.
Anime has probably only been allowed to get away with what it gets away with for so many years due to simply flying under the radar.
Go Nagai hated the Japanese PTA to the point he had them all violently killed in one of his mangas.
And Gundam IBO caused a similar shitstorm when it was airing. * although they had a point about that one I think *
