Many men who consider themselves part of the movement use men's rights as an excuse for misogyny. They are not real advocates for men's rights, the same way that feminists who want to be superior to men are not real feminists.

The issue arises when the general public encounters these people and assumes that the entire men's rights movement is like those false activists. Men do have real issues. Every demographic group does by the nature of society. You can argue about which issues are genuine concerns, but you cannot discredit the entire movement based on a few bad advocates.
