Not a single genderspecial claim to aberrant genders or sexual fluidity is backed by so much as a single word of hard science. There is not, as of this moment, a single credible, peer-reviewed study proving the existence of any claim to anything they claim.
I spent months researching this shit for Vade's article and later conducted additional research as the Farms increasingly covered people who whine about being NonBinary. I have not found a single piece of scientific evidence backing any claims made by these nutjobs. The closest I even came was finding reports cited by the likes of Mark Boyd, which had studies that were fundamentally flawed, not peer reviewed, or my personal favorite, self peer reviewed.
There is not a single cow we cover who claims to be a non-standard gender that has given any proof that this is the case. Evidence overwhelmingly thus shows that their bullshit is nothing but bunk and deserves to be mocked as such.
Another good one is to bring up population demographics. Transpeople account for less than 0.003% of the human population. That's going by census figures. As such, they're such a minority that they aren't getting any help without the good graces of cis people. In terms of numbers, they amount to a grain of sand in an olympic swimming pool. Your average person will go their entire lives without running into a single transperson IRL. As such, being hostile towards Cis people is essentially mandating that they stay ostracized.
They can't defend against these other than whine that science is wrong.
It's the fucking silver bullet. Use it against a Genderspecial and they automatically lose.
Rani. Dead Gods was actually enjoyable. Recommended if you want a half-hour time-killer.
Exaggeration for comedic effect, though we do have plenty of examples of the usual suspects blaming everything from mass shootings to presidential elections on Gamergate.
