Not everything is about male appropriation of female things.
No, but this is.
MtFs are the driving force behind it. They are using transmen to further their agenda.
I'm not at all disputing that transmen don't object to it, I'm sure they do. But it is transwomen who will be nailing it home, time after time.
Transmen are women. Their voices are as irrelevant as any other woman's. They're not clamouring to get into men's spaces, to change the definition of the word man, none of it. They are not online telling men how to be men.
Or if they are, no one is listening.
This case is no different.
Transwomen actively do not want this specific parts of womanhood that relate to biology to be designated as anything to do with women.
Hence the pussy hat outrage on the women's march.
And I completely agree, it makes no sense. Because it's not about them wanting to be women. It's about them not wanting women to be women.
