That's it, John. I'm ashamed to say that, as a teacher of 25 years' standing, I never heard the issue raised even once. Jaysus, that does not make me feel good. But the signs are that awareness is increasing and that times are changing. Today we embrace and celebrate gay people. Maybe in thirty years' time we'll all be the same about transgender people. There will be plenty of akenaton-style obstacles along the way, no doubt. I stopped finding jokes about transgender people funny several years ago. Life's a work in progress, innit.
