[animation] is a medium for any subject and any audience

I fully agree.

I think there's a misunderstanding here. I don't mind when such themes is used as a part of the story, what I am complaining about is the forced ecchi aspect that is prevalent in most Japanese animations. Otherwise, If you remove that, a lot of anime may as well be for kids honestly.

When I was still watching anime and a ecchi scene was randomly thrown at my face. I wasn't like : "that's nice" or whatever they expect me to feel, it always felt awkward and I end up asking myself what was even the point of that ?
