I'm not convinced Trump thinks about us any further than just getting his piglets to squeal at a rally. He'll be more cruel if he gets around to it, but immigrants are who he's liable to actually commit a genocide against.
Tbh at this point I'm not to worried about it, at least in terms of legal stuff. Getting gender affirming care is probably going to become a bitch, and its not like hes going to oppose any anti-lgbt laws stateside (not like Kamala would either, lets be real), but I think Trump only cares about being against transgender people as far as getting elected. Once he's in office he's probably going to have other things to focus on.
I'm a little more concerned about Vance and the alt-right groups that'll be emboldened by this though. Kinda hard to tell what'll happen with them at this point, and I do feel worried about an influx of hate crimes being possible.
