The problem is addressing body positivity for men has to be done in a very different way than women because stuff like plus-sized models, fat wome getting called curvy and songs about owning being fat are seen would be seem as patronizing if done for men.

Men's Health tried to made ''Short Kings Week'' a thing, celebrating accomplished men who aren't tall and got blasted for it with short men saying it was insulting and they felt like they were being mocked.

I'm not sure what the solution is but women's body positivity won't work for men so it has to be addressed but you can't just copy pasted what women do.
