>>2657First, "their genres" are set by totally random people, most of whom are newfags. Second, genres of anime are an extremely flexible thing, and their boundaries are not set in stone. I'll give you examples if you want.
Shounen is defined by demographics of manga magazine which published the original work. But, most of LN adaptations are also shounen.
Seinen is defined the same way. But, adaptations of proper novels are seinen too.
Slice-of-life is not obliged to have any moe, or any female characters at all.
Yet again seinen is not obliged to be "dark & bloody & gritty", it can be quite lighthearted.
Josei is not obliged to contain romance, or to depict realities of life of adult women. K-project is a total battle-josei, so to say.
Galaxy Express has nudity, implied prostitution, and a whole other can of worms, and yet it is kodomo/G-rated, and it aired in a family-friendly timeslot.
Koe de oshigoto and a couple more of shows listed above have barely censored dicks on screen, and yet they are not hentai. Majority of Go Nagai shows have sex with hardcore perversions, and yet they are not hentai.
Contrary to what you are saying, I've seen many, many newfags dropping Wicked City with the wording of "ewww it's hentai". While in fact sex ≠ hentai.
Yet again, when a typical western viewer thinks about "hentai", he thinks of non-stop fuckening with zero plot. In fact, "all of those" do not fit this definition. They excel in ecchi field first and foremost, and sex scenes do not end in themselves, not to mention in Tezuka movies they are veiled in a much better way than sex in some examples from above.
Sex ≠ hentai. Ecchi and hentai are not mutually exclusive. Think outside the goddamn box, think with your own head, and judge the shows on a case-by-case basis, instead of lumping them together in some arbitrary categories. If it causes such disputes,
the whole list should be renamed to "Anime Erotica". A simple yet effective move, isn't it?
