Oh my giddy aunt, I honestly thought that account was a parody 
I think we need to stop characterising parts of this movement as silly, and start taking them deadly seriously. These people aren't kidding: they see value in enforced thought, mandatory obedience, the usefulness of lies. Civilisation doesn't naturally always get more progressive, but that's what this type of person wants you to believe, when actually they're pushing for the opposite.
This is exactly what Timothy Snyder highlights in "On Tyranny", which looks at the behaviours that are necessary to enable a totalitarian society to flourish.
He talks about the danger of "heedless conformity" and "anticipatory obedience" in enabling people to rob you of your power. We have to resist. He says the truth dies in four modes - the first three can be seen in action anywhere within transactivism. The fourth isn't fully formed yet (or is it?).
- open hostility to verifiable reality, which takes the form of presenting inventions and lies as if they were facts (such as the anger with which the statements "women don't have penisis" or "lesbians are female homosexuals" are greeted. Or the fervour with which the lie of razors behind stickers raced round the world. Believing clitorises are short penises. Males have ladybrains. I could go on for a long time on this one).
- shamanistic incantation (Transwomen are women)
- Magical thinking or the open embrace of contradiction (humans can change sex; transwomen are the same as women, but women can't be transwomen. Again, many many examples of this)
- Misplaced faith. I think this is still forming, but the whole genderist position is a faith-based one- what is a gender identity but a soul by another name?
I'm sorry to suck the fun out of the thread, laughing at complete dolts is generally something I am right up for - but this genuinely worries me
