I am not trans, but I've been putting together a similar plan to evacuate my trans nephew from the red state he's in, to here in California.
I unfortunately don't have the resources to potentially help them get out of the country, but I have family who do, though I haven't actually broached that subject with them (and I suspect that broaching it at this point wouldn't go anywhere except making them think I'm being alarmist).
Right now it feels like watching a storm build on the horizon, and trying to figure out how bad it's going to be when it gets here.
