This argument literally makes no sense. Who cares who created it? It can be revised and made better. Practically everything in our society was created by men. Are you trying to imply that we should (assuming feminism is the right, which you don't believe) restart society? I don't get your point.
1. Feminists often respond to claims that feminism ignores men and soley focuses on women by saying they're fighting for the acknowledgement of "femininity" rather than strictly "womenhood".
2. Feminine is a socially constructed gender role, womanhood is biological love.
3. With this logic feminism is basically fighting to say that lipstick, high heels, and other markers of femininity can be associated with strength too. (as you said last page) But I'd say no, for example high heels can't be associated with strength because they're extremely impractical, painful, and weaken the wearer rather than making them stronger, they're objectively worse.
4. You can fight for women without fighting for femininity.
