So... feminists determine which men are MRAs?

It seems that the ability to decide for oneself is being more and more removed from men, by women. It seems like feminists determine who is an MRA (anyone who doesn't blindly agree to feminism), a misogynist (anyone who disagrees with feminism), and a misandrist (no one). But women are still able to decide for themselves if they will be feminists or not... Why don't men have a choice?
