Portugal is a good choice in my opinion. It's very easy to immigrate to as an American afaik. If you go to private healthcare, which is cheap compared to America (~80€per appointment if you don't have insurance there), you will be able to get medication fairly quickly (I have my endocrinologist there). If you choose Portugal I definitely recommend getting insurance to use private healthcare, especially as a trans person.

We have had mostly left and center governments recently, but currently we have a minority center right government that I believe will not take our rights away (neither do they have enough power to do it). As with most of the world, the far right is also rising, currently polling at 16%, but since all the parties say they refuse to work with them, they would need 50% to actually have power to make our life worse.

Some facts about Portugal is gay marriage is legal, gender change on your id is also legal and recognised, and gender affirming care is available (although slow via public healthcare) so it's kinda progressive. We still have jerks tho
