I feel sad for their outcome. Surgery regret however is extremely low for trans people, so the furore over one case should not be taken out of perspective.
Research by Prof. Dr P. T. Cohen-Kettenis, VU University Medical Centre, Department of Medical Psychology, shows that of 162 trans adults, only 1 reported they would choose not to transition again. Another had some regrets but would choose to transition again (0.6% regret rate) Sex reassignment: outcomes and predictors of treatment for adolescent and adult transsexuals.
Reality is, especially in the current system, this individual will have gone through years of waiting and counselling to get to surgery. They also would have been informed of the risks and signed a disclaimer. So I cant see how they will be successful.
But evidence is that majority of trans peeps going through this surgery do not regret doing it. Let's face it, no-one does surgery on a whim, no matter what for.
You don't stop surgery that improves peoples lives for the odd case that regretfully is not what they wanted or didnt work out.
It's not experimental, it's at least 50 years of experience now.
So no, one odd case out, doesn't mean "what you all said was coming" has borne the fruit the OP suggests.
Let's be a little kinder. Support this individual, but also those who feel the need for surgical intervention.
