Why is there fat acceptance but not "short acceptance"?

Men are suppose to put up with fat women even though almost all of them can slim down if they want to

But it's OK for women to discriminate against short men even though short men can't help it at all
(I'm not short by the way)

Why the double standard?

Basically women's desires are OK but men's desires are not?
