That's because men as a society associate anything feminine with being weak. That's why when a man does something "girly" or is too weak to do something they call him a "pussy" or a "fag" because these are words that are associated with femininity. They're told to "suck it up" and "be a man" as if having feminine qualities is a bad thing. Men aren't allowed to be empathetic or show any emotions other than anger. Men (as a general society, not every single individual man) still think they're better than women, which is why equality hasn't happened yet and feminism is still a thing.
