Not the most absurd law ever. It just states that minors can’t undergo life altering surgeries or take medicine with potentially irreversible effects (that apparently isn’t even approved by the FDA?). It says nothing about what children can or can’t wear. Only thing that to me makes me raise an eyebrow is the whole “children can’t be encouraged to hide this dysphoria from their parents by teachers”.
I would also like to see the studies cited, but if they’re valid, then the law is for the most part reasonable
