Well.
I'm not really sure what to think and I rambled quite a bit and I wish I'd been more organised in my approach but he spoke to me for an hour (totally overrunning his surgery time). He recommended two ways in which I could take my concerns about self-id and assorted issues further.
He was perfectly lovely, listened intently and took lots of notes. I did not manage to dissect the law on the female participation on boards because we spoke mostly of the wider issues women face when they would like to discuss the possible impact of self-id on women's rights. He was entirely unaware. And not happy about what is going on.
I have decided to follow his advice and take this further as suggested. Anyone who is interested to join in, please PM me.
