There can and will be multiple class action lawsuits. Like nothing we've ever seen before. So it's just a matter of which plaintiffs are bringing which lawsuits against which entities/individuals. One of the major hurdles of getting through a class action is establishing that the members of the class are sufficiently similar enough in their interests and the harm they suffered in order to proceed as a class. So I imagine there would be class actions that go after different players, some within the same suit, but different targets include: individual doctors/health care providers/surgeons, pharmaceutical companies, gender clinics, hospitals, pharmacies, school districts, LGBT organizations, maybe even the FDA, possibly health insurance companies, etc.

It's often a matter of finding the right plaintiffs against the right defendants in the right jurisdiction to get the best chance. But yea I imagine lawsuits against surgeons who perform gender reassignment surgery. They may go after the worst of the worst in terms of quality of surgery first to establish good precedent. There is some abysmal work being performed out there because it brings in $$$ and is not being monitored or scrutinized.

Class actions are really slow though (like, expect over a decade of this). That's why they tend to settle, and we wouldn't want a settlement before discovery. Oh also, this wouldn't be a class action, but kids suing parents is going to be a thing. We may have to wait a while for this though and I feel so awful for all of the harm that will be suffered by these kids in the meantime and the feelings they will feel as they try to make sense of and salvage their lives. I am waiting to see what happens with Jazz Jennings because even though Jazz is touted as a success story, Jazz's surgeries have been profoundly unsuccessful. Jazz also has the face of a little boy on what appears to be a grown woman's body. How is that going to age? Jazz is still SO young. I really don't think we've seen the depths of Jazz's tragedy.
