Feminism does good for men, too. The hyper-masculine ideals of what men should and need to be are created by the patriarchy, and feminists regularly deconstruct those ideas and fight against the assumption that all men need to fit into that box.
One last thing about men: Most feminists do not hate men. It is true that men benefit from the systems set up today so that they occupy 81% of the seats in the US Congress, 95% of the CEO positions at Fortune 500 companies, and make a dollar to a woman’s 77 cents in the US. But this isn’t about hating men. This is about finding a balance.
