Interesting post, this has been on my mind as well. I'm more or less center-right and liberal (in the European sense of the word), so more on the right than left, but I share your concerns about some of the policies being put forward by people like Milei, who I think you correctly classify as far-right. I see how some of the policies supported by Milei (and others like him) go against the Bitcoin ethos.
Although I think it's positive that Bitcoin is being endorsed by popular politicians, I think it's a shame that this happens almost exclusively on the right (there are some exceptions). And, I also see how it being endorsed by far-right politicians can make people on the left despise Bitcoin, even when they know very little about it.
It's an even bigger shame when you consider the fact that Bitcoin can contribute to social justice and equality. It doesn't discriminate against anyone, and it's an inclusive system. Interesting for people on the left, you'd think. Although, a fixed monetary supply goes against Keynesianism, but that's a discussion for another day.
I disagree with the statement that the right is in favor of state control, centralization and the suppression of human rights (although historically you might be right). Even though part of the right might favor this, the right-wing parties in many western countries support (or campaign on) freedom, sovereignty and individual rights. I am European though and the right-wing here is much less socially conservative I think (almost nobody even thinks about banning abortion or loosening gun laws, for example).
These are my thoughts, I have mixed feelings about it too, but I definitely agree that we shouldn't pick a candidate solely based on their stance on Bitcoin.
