It takes a lot to bring a legal suit so they want to see what other people do first.
Yes. A lot detransitioners were suffering from mental health conditions in the first place (why they transitioned) and are now having to deal with the fallout. I expect many of them won't feel strong enough to pursue a lawsuit. A lot of the detransitioners I see on YouTube just want to move on with their lives and put this behind them.
However, if Keira Bell wins, that might inspire others to come forward. And if the UK cases start to win, the American lawyers will start circling.
None of this is good for the men and women who bitterly regret the path they have taken. If they have had mastectomies or hysterectomies or castration (can I say that or must I say 'bottom surgery?'), that's irreversible. However, it might stop others from going down the same pathway without proper checks and balances in place.
Kellie-Jay Keen Minshull interviewed the mother of a transitioner on her show a while ago. (The interview was removed by YouTube but you can find it on other platforms.) The mother said she knew a woman whose daughter fully transitioned in her late teens and then realised in her early 20s that she had made a terrible mistake.
It was heartbreaking.
