Give them a bit of slack, people with gender issues have immense psychological problems to handle, which most of us can't imagine - generally speaking, they're getting a bit of slack.
I believe in the freedoms we have in the West, including adults having autonomy over their own bodies.
So, I fully accept people are free to have surgical operations on their bodies and identify how they choose.
One issue here is that some places of work have become infected with the trans activist mind virus, and people are being compelled to address someone with that person's chosen pronouns. This is profoundly illiberal.
Example: Caitlyn Jenner is free to transition and call herself a woman. And I'm free to either accept or reject that claim. I'm free to either call her a woman, or call him a man and use he, him, his. Freedoms cut both ways. <--- this is how free speech works.
The OP's issue is ridiculous, if true. <---- Edit: just read the link and it says the person regrets being allowed to transition before adulthood. This is reasonable. Only adults should be allowed to transition.
But, I'm gonna make a prediction: expect similar lawsuits in the coming years. Gender reassignment is still very new. We don't know how badly people can be damaged from having their bodies sliced n diced, and taking hormones for the rest of their lives.
And here's an opinion that would get me in trouble on FaceBook or Twitter: I think the old fashioned way of treating people who suffer from gender dysphoria (recognising it as a mental problem, so psychological treatment) isn't as bad as mutilating an otherwise healthy human body and stuffing it with hormones.
At least psychological treatment can be unravelled. OTOH, once a person 'transitions' there's no way back if, later down the line, they discover they're not actually transgender.
