In stable societies the power ladder is at least partially correlated with creating added value. Getting people to buy your product, getting people to elect you into office, even helping out your friends so one day they will help you haul that fridge upstairs. They also have some checks and countermeasures, like the universally trusted independent judicial system, that somewhat impedes attempts to break this correlation. Except now it's breaking apart.
Now we have a growing socioeconomic group that wields increasing power over what others can say by just claiming that they are fighting for a good cause. As long as you are anti-$BUZZWORD and have a sufficient network of followers, nobody dares to oppose you and nobody will protect those who dare.
It's not really about what is in the book or what pronouns someone uses. It's about the fact that a power-hungry person can have the pleasure of telling 1000 other people what to say, and financially obliterate those who don't comply. And no, there won't be a happy blissful day at the end of the road when we have finally eradicated all friction points and everybody can go have a beer together. The power-seekers won't self-disband. They will keep finding a target after target because that's where they get their kicks from.
Entire fucking history of USSR is littered with different power-hungry people using noble goals to chop their competitors' heads off. It didn't end well for them and it didn't end well for the country. I'm happy we are not at the head-chopping stage yet, but I keep wondering how long do we have left...
