If women aren't morally compelled to find short men attractive, why are they morally compelled to not feel negatively about them in general? I don't see how anyone is morally obligated to feel any way about any other human.

It's just really weird to me that some people get angry about being short (understandably so) but instead of just admitting that, they turn to some kind of universalist morality as a way of shifting the burden to others
