Not all of them are.
By and large, alt-right men don’t seem to be forcing these traditional gender roles on the women of their movement—the alt-right women are doing it themselves. The women share a profound disdain for the feminist movement, and are eager to claim the supportive, behind-the-scenes roles.
As for female empowerment, there’s nothing that has made me feel more empowered in my life than supporting and being supported by a strong man,” Claudia Davenport, an alt-right activist, said in an interview with The Economist. “I think that men and women are better off when we stop fighting nature and allow our distinct identities to shine through.”
Most alt-right groups are predominantly male, but we should be careful in assuming that there are no women who support their views or that biological determinism is a viewpoint only held by men.
