My GP recently referred me to an online support programme for anxiety. I got the link to it today and went to sign up, and one of the first questions was what gender I most closely identify with - male, female, or other/prefer not to say. You had to choose one to continue, there was no question for what sex you are and no option to say you reject the concept of identifying as one sex or the other.
Everyone losing their mind and adopting this surreal belief system has been a huge source of anxiety for me over the last few years. I'd laugh at the irony of being forced to go along with it to access help for my anxiety, if it didn't make me feel completely deflated.
