I guess like that you want to consider cultural context in reference to gender roles (even though those roles only exist to keep women subordinate, regardless of the culture), but you don’t see any problem with a man appropriating womanhood. For the first one, you recognize a power imbalance and think about coming from a place of privilege and potentially taking something from a culture should be carefully considered. For the second one, you don’t recognize a power imbalance and believe that your redefinition of woman is better regardless of women’s feeling on the subject. I feel like it might be worth reflecting on why patriarchal structures receive more consideration from you than females do.
