Group tendencies don't preclude the existence of exceptional individuals. Your mother might be saintly but that doesn't apply to women in general.

My saying "women don't have moral agency" is a linguistic shortcut and somewhat troll-y and I will admit might not be the literal truth. But if it were true it does explain women's behavior in the overwhelming majority of situations.
