I don't deny it, there are huge parts of anime that are pretty awful. But "a lot of it" seems a bit of a blanket statement, majority of the anime that makes it into the spotlight have underlying tones that are relatively mature. Even anime that I think is shit have this (Yuri on Ice), as well as the shows I enjoy having those awful qualities (Negima). Think what you want I guess, but I find that most anime have the same tropes that live action shows have as well, the only difference is it's a cartoon.
Nah there's a huge cultural gulf between live-action American shows (and even American cartoons) and anime.
