"Man" is not a role, any more than a "woman" is.
That's the entire point of our belief.
It's a statement of biology and nothing more. A man (male human) can play any role. But they can't be female, any more than they can be a dog.
There's a three-way fight here
(a) genderologists - men should be able to play the "woman" role, women should be able to play the "man" role
(b) right-wing - men have to play the "man" role, women have to play the "woman" role
(c) gender critical - there should not be any roles
If Lekisa wants to argue against group (b), then Lekisa should go and find some members of group (b). We're group (c) here.
Because this is a feminist forum, so we don't think women should have to play a "woman" role. The clue's in the name.
