Cis strikes me a harmless and reasonably useful word.
I get that you don't agree, but you can't act like some holy annointed holder of Truth! and Feminism! and expect everyone else to See the Light! just because you the share the same few anecdotes over and over again (obnoxious brat at Edinburgh uni, creepy fucker from Canada who claims to be a six year old girl, prisoner with 'seven inch surprise', here you come again).
Ffs, when someone put up a post inviting people to the women's march the first posts were all 'So does that include trans women? Because if it does I'm not coming'.
How distorted does your worldview have to be where transwomen are more of a threat than Trump? How can it be comfortable to have a position on transexuals that you share with the Republican party, the most retrograde part of the Catholic Church and the kind of 4/chan-ite who tweets holocaust jokes and is all 'cuck' this and that?
How can it make sense to believe
A) Transwomen are cheating if they don't cut their dicks off
B) It's obscene and tragic that people with gender dysphoria are pushed towards surgery.
Gah!
(Yes, I'm female. Vulva vagina and all the rest. Yes I define as feminist. No, I don't think all feminists should agree with me. Yes on the whole I'm gender critical. No, I don't think everyone should agree with me on that either.)
