Everyone is a natural advocate of their biological sex whether they like it or not. Those who don't just have poor confidence in themselves. One does not need to be out protesting to bring about positive change. Just changing your demeanor and treating other perspectives kindly, with compassion and reason, is enough.
Feminists are presently a by-product of extremists who want undeserved matriarchal superiority. Feminism has been co-opted by insane cat women, whores, and insane men in dresses. For these reasons, most positive advocates for change now identify as "womens rights activists", and now may even serve as mens rights activists because the core of true feminism was always about providing a positive environment for both sexes to thrive in society.
