The chick in the vid actually looked like an adult (for once) but I will say this:

There is an popular anime that constantly sexualizes kids. One notable moment that finally made me drop it involved an older brother giving his little sister an orgasm by brushing her teeth. /r/anime is pretty quick to tell you that weird stuff like this happens in that arc (even though its definetly not abnormal for the series) because apparently that book was never intended to be released to the public. The author wrote it for his private uses.
None of them seem to get that this explanation makes the whole thing even weirder. Why did he write it? If the smut was just for his private time why didn't he imagine the characters as adults? Who knows.

Every now and then in one of their little Why do people give anime (fans) so much shit for sexual content threads one of them will make the mistake of unironically saying something like "People don't freak out about movies like ____ but they complain about anime" where they once again seem to be oblivious to the fact that the women in those stupid movies look like adults while the panty shots and worse found in anime often involve characters designed to look like children ...

So.. yeah. Not suggesting anything about them. Just leaving that there..
