The least we can say is, the feminine is defined as the negation of masculine. Whatever masculinity is, the feminine is not. This is why I follow a whole tradition of French feminists dating back to Beauvoir in saying that society codes men as the self-same subject an women as the Other. We contradistinguish the self from the Other in the same way we contradistinguish the masculine from the feminine. It's not arbitrary, it's empirical. We look at the dominant culture and notice its self-centeredness, its tendency to make everything about it self, and its ignorance of any view other than its own. From all this we conclude that dominant culture, the phallocentric patriarchy, represses a different kind of culture, one more focused on diversity, community, and relationships. Feminine culture just is that culture which mainstream masculine culture occludes. Yes, feminine culture is oppressive in some ways too, but I think we can all agree that masculine culture oppresses feminine culture more often than the opposite. We can see the ways patriarchal ideology blocks out feminine culture when we look at the ways redpillers tell men to relativize everything to their own male desires. Everything becomes all about getting what you want and the woman's desires are ignored totally. I'm telling men to pay attention to the desires of women.
I talk about the conditions that enable gender identity. I don't need to give a more determinate definition of femininity and masculinity. What makes a behavior masculine or feminine? Society. As a collective we accept specific kinds of behaviors as defining some genders and not others. It's useless to try and cast doubt on the fact that definitions of our genders do exist. We know some qualities that society classifies as masculine and feminine and that's all we need to know. We don't need to list out all the qualities that count as feminine or masculine. All we need is for a masculine culture to exist in a negative relation to a second culture different from it. If there is no culture different from the one culture, then the second culture, the culture of diversity really does get eliminated. I'm proposing we preserve an alternative to the patriarchy.
What it comes down to is that masculinity refuses to resemble femininity. It tries to separate itself from its other. Traditionally masculine people refuse to ever act feminine. If there is no culture different from the culture of the self, then the patriarchy has won. After all, what is feminism without the feminine perspective?
I never claimed that all behavior reduces to either masculine or feminine. I said that I know no non-gendered behavior that will help us fight the manosphere. I also claimed that feminine behavior will help us fight the redpill ideology. You've yet to give an argument for why feminine behavior will fail to fight the manosphere, thus you might as well give an example of a counter-patriarchal gender-neutral behavior. Otherwise gender-neutral behavior does no damage to the oppressors.
