I mean, this kind of argument is a bit stupid. Are we supposed to not recommend any books because garbage like Mein Kampf exists (and is infact still printed today)? That's some certified Grade A trash that is permanently associated with books (or more specifically, the book genre Autobiography or Philosophy).

It's not a genre, it's a medium. And most of the bad stereotypes of anime are only universal in a certain awful genre or two.

Although the worst is the most popular, I'll give you that.
