It has been made clear that any attempt to tailor a law so that it would predominantly affect a specific person or specific group, as it would in this case because even if it applies to all trans-folk, it would specifically primarily impact this one individual and has been said to be for that purpose (particularly damning).
Not that precedent means anything, so any attempt to litigate that winds up in front of the Supreme Court could go either way. I would hope that even they would see the pettiness here and follow precedent.
I'm not sure of the specifics of the Florida/Disney cases. I do know that it probably could've at least been argued that the law was too narrowly tailored, but I'm not a lawyer or a multi-billion dollar company and maybe there are reasons.
We've had our democratic say. Anything further response from the people will not be democracy. It'll be the same thing the French people said to their aristocracy. The same thing the Russians said to the Tzars.
