I like mangadex, but i must say there is many problematic things here that should be talked about and deserve a serious discussion.
I won't talk that much about the gross "hentai" content, which is something mangadex should not host for reasons that don't deserve an explanation. But i must mention some less obvious, like
many mangas depicting improper relationships between womens, or even mens. It's completly disturbing and should not be public, maybe except for mature intended audiences. Seriously, think of the childrens.
Also, i must say there is a
lots of educative mangas here that should be a source of concern. Many of them are of bad quality and teach things that are either wrong or just not worth it. Teaching is something that should be done by professionnals, not unqualified mangakas. Education is a thing for well selectionned teachers. Also, a lots of them teach concerning theories, like the very controversial Theory of Evolution, that don't fit the holy message of the Bible.
(Seriously, my mirror self talk like a karen, i don't know why, i'm anxious. And i think it's a mistake : my mirror-self is ranting like hell, which is French as fuck to the point even i should be jealous to the core).
