"feminism" has become a weasel word. There is no feminism if men can be women and and womanhood is considered "a feeling". Feminism has been co-opted by people who have an agenda, feminists didn't push back, the movement is now rotten to the core. unfortunately feminists themselves are to blame, because they pushed intersectionality which is divisive by nature. As soon as you reason about "subcategories" of women, this is what happen, you are building a hierarchy in your own struggle. It was a terrible mistake, no matter how well intended intersectionality was.

So your friend has been misled as to what feminism is at first place.

Men are not women and feminism was never designed for transsexuals. Gender stereotypes need to be fought, not normalized and enforced through the idea of "gender".
