Someone wrote that a certain percentage of transitioning men (not all by any means) see women as competition for the woman they identify with (and adore) inside themselves. Perhaps as romantic competition, perhaps as sexual competition, perhaps as competition about who is the most beautiful or who 'womans' best (makeup use, heels, dresses).
Those individuals are not going to care about women's rights or feminism. They don't identify with women, only as women, and several express open anger, hatred and jealousy at what they call 'cis' women.
As an aside, I have read several young detransitioning men state that they transitioned because they wanted to be beautiful women.
Not because they wanted to be women, but beautiful women.
When I saw that, I realised that there are some transwomen and male trans activists who are not trans themselves who seem to think in those terms, i.e., what a woman is and how much woman someone is should be defined by how appealing that person is to men.
So you could lose your right to be called a woman if they regard you ugly.
