Being an alpha woman is very different to an alpha male. Having a bunch of rich beta cucks to worship you and give you everything you want is top tier alpha womaning. She has all the social power and all the orbiters she can dream of, that's the most "alpha" a woman can get.
Feminism is and always will be an attack on the traditional family. No matter how "cool" you think your girlfriend is being by acting like a man (this makes you gay for liking it BTW), it's less children and less motherhood. If you're into homosexual relationships then go ahead and date your "cool feminist" woman. But straight men like women to act like women and that means being against equality in all forms and feminism in all days because they're not the same thing and both are cancerous as fuck to the family. We live in a society where the average relationship is a homosexual relationship even though it involves straight people. Try to figure out why both people are trying to be men and consider exactly how straight it makes you to want to date a woman who acts nothing like a woman but smells nice and makes your dingaling hard.
