Does Egalitarianism enable more Gender Equality?

If everyone is equal, it’s much more acceptable for women to get to the top. In societies where no one is special, men seem much more accepting of female leadership. Whereas in hierarchical cultures, where subordinates must bow to their bosses, female managers and politicians are more strongly disliked. They may even trigger backlash. This is a novel theory of gender inequality. I believe it helps explain why Russia and Nigeria’s parliaments are almost entirely male, just like Korean and Japanese male-dominated management. If I’m right, then Scandinavia’s feminist secret is not so much about gender, but rather an evolution of moral and political egalitarianism.
