Okay, I keep getting being told that no one is denying that sex/the female sex exists, and being asked for "proof". Collating here. Feel free to add.
"No one is saying sex doesn't exist" - also, trans women are adult human females. #nooneissayingsexdoesntexist
Trans is female. #nooneissayingsexdoesntexist
A variant: sex exists, but male and female don't. #nooneissayingsexdoesntexist
#nooneissayingsexdoesntexist but gynaecologists should treat transwomen.
#nooneissayingsexdoesntexist Well this one's quite clear.
#nooneissayingsexdoesntexist But the word female is now redefined.
#nooneissayingsexdoesntexist Maybe this was meant ironically? Let's hope.
#nooneissayingsexdoesntexist I'm going to be honest. This file was saved on my computer as "It's Naomi, because of course it is".
#nooneissayingsexdoesntexist Honestly not sure what this is even saying, but a woman can't be -mostly- male. No one can be -mostly- male.
#nooneissayingsexdoesntexist Ah, the classic female penis. That's going to be in this thread a lot.
#nooneissayingsexdoesntexist It's just a sort of rough guess.
#nooneissayingsexdoesntexist Oh no wait, it's genocide.
#nooneissayingsexdoesntexist Damn doctors, amirite?
#nooneissayingsexdoesntexist I mean, technically, I guess they're saying that sex does exist but it's decided by gender? Not actual physical differences. So I'm not sure what the word "biologically" is doing there.
#nooneissayingsexdoesntexist Sex exists, but male and female don't. Gotcha.
#nooneissayingsexdoesntexist Trans women get periods. I mean, this isn't technically denying that sex exists, but it's pretty strongly against biological facts, so I'm including it.
#nooneissayingsexdoesntexist Now I read the first tweet here and thought "Maybe they're just making a linguistic point about 'woman' vs 'female'". But reading on, nope, they're definitely excluding sex from the discussion. Quite remarkable how hard they work to avoid the word.
#nooneissayingsexdoesntexist Or, if it does, it's transphobic to ever mention it. Ever. Even if it's relevant.
#nooneissayingsexdoesntexist "It's complicated". And has no practical implications that anyone should take note of at all.
#nooneissayingsexdoesntexist Yes, females can impregnate other females with their female sperm from their female penis.
#nooneissayingsexdoesntexist Sex *might* exist, but if you mention it, you're a literal Nazi.
#nooneissayingsexdoesntexist This one might be someone trolling, since Pliny the Elder is well-known for having got lots of science really, really wrong. If not, they're well-named.
#nooneissayingsexdoesntexist "Adult Human Female".
#nooneissayingsexdoesntexist PSA: If you were not born female, and you're bleeding down below or in your urine, please seek medical attention. Not being ironic or snarky, here, this can be a sign of cancer.
#nooneissayingsexdoesntexist The infamous "gender unicorn" that says sex is "assigned at birth". (Incidentally appropriating language used by the intersex community.) And others intersex people.
#nooneissayingsexdoesntexist "biologically male" is just a relative term.
#nooneissayingsexdoesntexist Another "it's complicated".
#nooneissayingsexdoesntexist Humans can change sex. Sex is a living system. You might wake up tomorrow and be the other sex. Or a third sex. Or anything really. A clownfish, maybe.
#nooneissayingsexdoesntexist It's mutable. Not cosmetically mutable. If you've had the surgery, you are literally the new sex. I mean, evidence might show that you're still taller, stronger, or whatever. But that's not sex, it's just luck.
This whole thread is worth reading on how sex and gender have been *deliberately* confused.

Clue, a menstruation tracking app, is keen to let you know that it's not just for females, it's for anyone who menstruation.

Special award to Twitter for deciding that the existence of sex violates their rules. #nooneissayingsexdoesntexist
Biological sex isn't naturally occurring. Also, it's not very reliable. #nooneissayingsexdoesntexist
That's not how sex works. #nooneissayingsexdoesntexist
#nooneissayingsexdoesntexist but you're not allowed to mention that only females get cervical cancer. BTW: https://www.cancerresearchuk.org/about-cancer/screening/trans-and-non-binary-cancer-screening#screening20 #OnlyFemalesGetCervicalCancer
Let's just conflate gender and sex again, shall we? 
Those boxes? They're gender. Trans ideology keeps insisting everyone has one, even to the extent of encoraging surgery on people's bodies to fit their gender box.

Apparently @ActionAidUK is a charity working with women and girls. I wonder how they know that? #nooneissayingsexdoesntexist
I wonder how Planned Parenthood Ottawa explains who might get pregnant if contraception fails, and what impact it might have on their lives? #nooneissayingsexdoesntexist
This sticky-out thing? It's a vagina. #nooneissayingsexdoesntexist
Having sex listed on birth certificates is an act of violence. #nooneissayingsexdoesntexist

The "violence" of saying that sex is binary. This person is a lawyer for the ACLU. #nooneissayingsexdoesntexist
Existing as a female... #nooneissayingsexdoesntexist
#nooneissayingsexdoesntexist except Janet here.
A woman is someone who is female. A female is someone who says they're female. There's another boring, technical definition but no one likes it.
