My understanding from Twitter is that in the case being talked about, they didn’t even do that. The state is claiming that photos show people under age in the audience, but they aren’t currently claiming that they have any more detailed proof.
This gets at the heart of the issue. Desantis, like all fascists (lately synonymous with republicans), only care about an issue as far as it gets them power. Transexuals are easy targets because they’re mostly unseen and their existence demonstrates a scientific/biological understanding of humanity rather than a biblical one (biblical in the sense of I represent God cause I’m parsing the bible at you). The problem with targeting transexuals is their lack of visibility in society. Transvestites on the other hand are very visible and have been part of pretty much every cultural since recorded history. So, if you are a craven power seeking fascist with a bit of state power demonize and attack the transvestites in grand gestures to demonstrate your power to those that worship power and legally drive the transsexuals farther into the fringes so you can keep using them as a scary monster to your ignorant base.
