One is (theoretically presented as) biologically female? Age differential? One of the two isn't trying to rape / molest children.
One is a fucking cartoon for fuck's sake. Most anime actually presents decent morals in, granted, morally ambiguous situations.
If you're speaking about the anime that's pornographic in nature, anon can't help you.
The VAST predominance of anime produced for public consumption is centered around teens, tweens, or even younger people. Anyone who's watched it would be able to tell you that they generally present decent morals and dignity.
Before anyone gets all butt hurt, seriously consider what the US shows its children… Honey booboo? The kartrashians? Woke ass sesame street? Woke ass <insert damn near anything here now>. Oh yeah, twilight? Teenage white chick has the choice between necrophilia or bestiality? Seriously we're showing a high school chick hooking up with a 140+ year old dude?
Stop complaining about anime until such time as you correct the media in your own country.
Anime isn't the devil. In fact it's far more tame than your average prime show.
