Been mulling this over for a while; thought I'd throw it out there and see if it makes sense.
I'm not keen on the idea of 'woman' being a gender identity, because it's antifeminist to tie the understanding of womanhood (female-bodied personhood) to an adherence to or preference for the culturally-specific shackles of our oppression; it creates dysphoria in women.
Yet I can truthfully say I identify as a woman - because I understand myself to meet the biological terms of that descriptor. (Shoutout to the feminist foremothers who pushed this prophylactic against female dysphoria!)
Woman (adult human female) is my sexed identity.
By definition, this identity can only be shared by others of the female sex.
But what of gendered identities? Who we understand ourselves to be in reference to the gendered world of pink and blue, fucker and fuckee, boss class and service human, skirts and shaved heads, all the sexist gendered crap we're immersed in - all our experiences in that world affect who we are.
I was groomed for the whore caste (csa), but my first conscious gendered identity was: resister. Through my teens I added broken; later I overwrote this with feminist.
I've since learned that the word for female resisters who assert a sexed identity is terf. There's sure as hell a gendered aspect to the label; it's used to silence females who resist patriarchal control of our language, and it's often accompanied by threats of sexual violence. It's a gender identity.
It's my gender identity.
But that's beside the point. The main thing I wanted to raise is the idea of sexed identities. Because we're always on the back foot having to defend ourselves, we're always being dragged into arguments over whether Woman is an identity or not an identity, when the question really is: is it a biological fact or a psychological identity?
Clearly it's both. One word with two related meanings: the having of the female body and the understanding of that having; and the former is both a necessary and sufficient condition within which to develop the latter.
The sexed identity of Woman is only found in females. Other sexed identities may be available, but this one is open to all and only female humans. And it matters. It's just as important, just as valid, just as equally fully human, as all the others. Yet it's consistently viewed as the worst abomination of the twenty first century.
Does this make sense?
