Very cool, if true

Yes, wrongful transition happens, but as Andrew says it's very rare. I read an anti-trans book that described six such cases, and as far as I could tell after some research, that's all the cases that the author could find. (I also discovered that, despite his claimed empathy, the author had never contacted any of his six cases, some of whom were quite annoyed at the way they were described in his book.)

But some have argued that because these cases exist, we should ban trans surgery. That doesn't follow. Useful statistic I read: a much larger percentage, about 20%, of people who have knee replacement are dissatisfied with that surgery. (I believe that: my cousin was one of them, and she was very bitter about it.) But we don't ban knee replacement.
