Cisgender person to MtF: "No you do NOT have PMS, stop cisgender appropriating. You as a MtF do not have a uterus or ovaries. PMS happens in the days after ovulation because estrogen and progesterone levels begin falling dramatically if you are not pregnant. Coming down from your estradiol injection the day "before injection day" is NOT premenstrual syndrome [assholes!}.
My neighbor is a black republican. He is against slavery, but for debt slavery. He believes in pro life ideas, yet uses condoms. He is a well intentioned, pro war conservative that only wants to help. He wants Trump to build a wall and ban Muslim immigration, yet considers himself a friend of the Mexicans and Muslims. He just doesn't make sense. I think he's a cisgender fag.
A ridiculous phrase made by the cisgender community to feel oppressed. There is not a specific "cisgender culture to appropriate". And, for example, a transgender woman saying she has post or premenstrual symptoms is not invalid or to be questioned. Firstly, how do you know that she has or has not had bottom surgery, and the effects of estrogen on a certain sample size? In fact, I assume you haven't looked into this whatsoever.
"You're cisgender appropriating our culture and experiences."
"Girl, what, I'm just saying cramps hurt like satan's ballsack."
