I'm going to give you an analogous anecdote. This might be outing if anyone happens to read this from my school.
Recently we had an inset about student anxiety and exam related stress. (Good, useful.) The assistant head introduced the session, and in her intro said about how student anxiety is on the increase. She speculated that that was because modern teenagers have so much to worry about now, "such as climate change". That was the example she gave.
Wtf? I sat there like, do you actually know any teenagers? Do you actually talk to the kids we teach? Yes I teach many anxious teenagers, poor things - they are worried about their exams, their parents, family issues, their friendships, their romantic relationships, or lack thereof... I promise you that for the vast vast majority of anxious teenagers, climate change is not in their top ten list of worries. They've got enough to worry about in their personal bubbles.
Similarly, the vast majority of teenagers do not give two shits whether you say "boys and girls" or "people". They have real shit going on.
My point is that these power-addled assistant heads, many of them, are simultaneously totally out of touch and peculiarly politically-motivated. They care more about being right-on than being actually useful.
