@taylan Thanks for sharing.
In my teaching career over a couple of decades I knew of one girl with Turner Syndrome. Admittedly I only worked in special needs schools occasionally, in which case a teacher may see a higher percentage of these. But they are incredibly rare and can pose great difficulties for those who have them.
The idea so beloved of activists that they *explain* that any of us could be any sex, both or neither, or change sex, and support these ideas is both absurd and rude.
