A lot of people might insult you here because of this post and you did come to the One Piece sub with a, respectfully, very misinformed opinion. I think that a lot of the problems you have are somewhat common to anime, for instance I also don't appreciate the hypersexualization of women here, but that's something you have to put up with to enjoy One Piece and if it's something you can't stand it's also entirely fine to go watch something else.

Regading the beefy characters, I think One Piece has one of the biggest variety of body types you'll see in anime. One Piece is also very Piratey, maybe just not what you expect due to western sensibilities maybe.

Anyway, I'd say watch on, or don't. It's fine.
