Well, of course they're proud. It's founded and run by Susie Green who used to be the CEO of Mermaids (still awaiting the result of the Charity Commission investigation into this troubled charity, aren't we?). She took her 12-year-old son to New York to get him onto cross-hormones and she then got him over to Thailand so he could have genital surgery on his 16th birthday, the earliest age you could have it done then (they changed the law subsequently as a result).
SG has spoken repeatedly about her poor little toddler son choosing to play with dolls, his father's horror and outrage, how she suspected his toy and clothing preferences might mean he was gay, how she acquiesced when her husband took all the dolls away even though it made her son wretchedly unhappy, and how her son 'knew' from an early age he was really a girl. Once she decided her allegiance was to her son, not her husband, she took this tiny child at his word and started buying him clothes from the girls' department, and putting him on a path to being a lifelong medical patient.
A more insightful person might have pondered how this kid had been told from his earliest years that he was doing boyhood wrong, that he was behaving like a girl, and that he needed to change so he would grow up into a man (presumably like his father), and, very understandably, he didn't want that. He wanted to just be himself. He could have been a little boy who liked playing with dolls and dressing up. He might have grown up to be a gay man. So what? What he needed was parents who accepted him for who he was and always had his back, with no need for drugs and surgery to make him a crude facsimile of something he couldn't be, with all sorts of health problems waiting in the wings.
Ever since, she has done her level best to put as many other children as possible on the same path. I could not despise that woman more.
