Obviously I expected the GOP would go from banning gender affirming care for children to attempting to do so for adults, but I will absolutely admit the speed they're moving through these steps is breathtaking.
The best I can come to understanding what they're doing, in terms of how unmooored it is from public opinion and what they'd want to do to win elections, is that they aren't anticipating a future where elections are held.
The best thing I can suggest if you are American and trans is to get the hell out of that shithole country!
