They were programmed to believe that everyone supports them for real instead of the fact that people just parrot the approved mantra for either woke points or to avoid drama. So when they end up facing reality, they are too indoctrinated to understand that it's not the evil TERFs brigading, it's regular people who are telling them exactly what they think.

It' s the same with passing: have you ever seen the comments down most TIMs's pictures in trans-friendly sites and subs? They are full of "You are gorgeous!" and "I would have never imagined!" when a quick glimpse to the picture in question would make everyone see that it's pretty obviously a man there. I still remember an article I read in which the author was absolutely confused about why marvelous specimen like Alok and Jacob Tobia couldn't get laid despite being gorgeous, smart and funny. There are at least three things that I consider wrong in that sentence.

And these same people cannot understand why they get misgendered when they walk down the street or why the straight man they want to fuck told them "I am not gay!" when they propositioned them.

Or pronouns: people use preferred pronouns out of politeness, fear or apathy, but using them convinces these people that everyone actually sees them as what they claim to be, so they are absolutely flabbergasted when, say, a child they don't know sees them and "misgenders" them.

Lies are bad, truth is always better. These people are lied to constantly and are too fragile, maladjusted or plain old disturbed to think critically and face reality. They prefer hiding in a comforting lie than the harsh truth. I kind of pity them, but on the other hand these are the same people who threaten anyone who doesn't kiss their ass. So as terribly petty as this probably sounds, I enjoy the schadenfreude.
