Not while "cis" assumes gender identity, thank you very much. I referred to t
hese girls earlier in the thread for good reason. They are a good example of sex based discrimination. No one gave them the possibility, let alone the privilege, of forming or choosing a gender identity before hacking them off this earth because they had vaginas.
Gender as a mere identity serves only to disempower women politically. It's a great ploy actually. Take away the words that define our difficulties. Erode their meanings then proceed to compare our experiences against those of some other another group. A great way to silence women (again). It couldn't be done by other than men in skirts and it's not surprising that they get support from men in trousers.
