To force a man to accept a conclusion (that a man is a woman and vice versa) against his own judgment is to order him to accept as true something that according to everything he knows is not true (is either arbitrary or false). This amounts to ordering him to accept a contradiction. It is like demanding his agreement that red is green. No rational man with high self-esteem will allow himself to do that.
One message of “1984” was that you could “rehabilitate” people to state a belief in lies; if you worked hard enough at it, you could brainwash someone into believing the lie.
“Star Trek: The Next Generation” actually did a really good episode about this. The captain was captured and a particularly cruel romulan was assigned to break him. And he worked on this with a very simply task — to make Picard see 5 lights where there as only 4.
At the very end, when it seems picard is broken, superior officers come in — there has been a political settlement, and picard is being released. Picard defiantly says “there are 4 lights”.
But later he admits to his first officer that he actually felt like he saw 5 lights at the end — he had been so broken his mind was ready to believe the lie.
This is what we are working on today, torturing people to believe a lie about something really ridiculous, like a pronoun. Most of us could care less anyway what pronoun a person wants, but that isn’t good enough, we can’t just USE the right one, we have to BELIEVE it is the right one.
Just try at your next diversity training to say “I solemnly swear to use people’s expressed pronouns in all of my work, but I also have to tell you that I will not believe they are correct”. You will get fired, and anybody who tries to defend you will also be attacked, like what is happening to JK Rowling.
