I think this is probably the case. I am a teacher and the ideology has infested schools, although mine has been a lot more sensible than many. We currently have one "trans" person who is virtually non verbal, autistic and has changed name / pronouns but nothing else - no visible signs, just a seat on the bandwagon.
I was at a debating competition (for 12-14 year old children) at Edinburgh University and there were a lot of instructions at the start about pronouns, which are now optional but which, of course, with kids eager to compete and be kind, were shared before each debate.
We need some sort of commission to root out all the terrible lessons, posters, attitudes.
