As I understand it, the law in Florida which Blake was referring to and feels IS genocidal towards trans, and a reason why Blake and Evie Brockman felt they had to leave that state, is the one which expands the death penalty to anyone who "commits sexual battery upon, or in an attempt to commit sexual battery, injures the sexual organs of a person less than 12 years of age."
I'm not a supporter of the death penalty for anyone at all, I've always been opposed on moral grounds. But this law would only be "genocidal" for trans people if the majority of them are thought to be sexually abusing children. Which sounds a bit transphobic to me as a proposition.
