I hope it has some effect. In the US many parents are effectively paying for their young adult children's gender clinic treatment through the family health insurance cover but obviously there are confidentiality rules in place so the clinicians won't talk to them directly. Many of these young people are also getting treatment through their university. It's different over there from what happens on the NHS here. Often a 18yo girl goes in and gets a prescription for testosterone at the second or even first appointment. Some of these young women have a history of mental health problems. The parents are trying to point this out and getting nowhere.
I suspect it won't be long now before detransitioning numbers start to escalate and that's when the lawsuits will start.
