You are looking at it from the wrong perspective in my opinion.

Bitcoin does not sit in any political boat and should not be linked to a political party or politician only because they praised it.  Anybody is free to hate on Bitcoin or to praise it, it does not mean there is a link between the two.  Bitcoin is independent, it can still work and run even if the entire planet turned to dictatorship.

In the same way, it is in my opinion wrong to hate on or love something only because a single person said it is bad or good.  In this life time, I have seen many people idolize something because a celebrity said it is cool or absolutely despise something due to a bad guy talking about it.  Trump can praise Bitcoin as if it is God, it does not make sense for somebody to hate on Bitcoin only because they hate Trump too.

No, Bitcoin has not become 'all right wing'.  Bitcoin can do the same thing for both wings and the center.  Rather, the right wing supporters found that Bitcoin fits their own set of mind.  Bitcoin does promote freedom and an alternative to the current very corrupt and dirty banking system.  But if Hitler was found alive and his last note was 'TODO: Make Bitcoin the world currency', does that mean it should be banned and hated on?  It makes no sense to me!
