People move across the U.S. a lot. I don't think it's insane to want to move to a place with likeminded people, many of whom share the same values as you do/

I think you should read the Wikipedia article on liberalism.

Again, from my experience that's mainly the extremists who took over the party IIRC last year. Most libertarians I know don't follow the MAGA stuff and are just against government mandates and overall big govt. I understand your perspective though.

I don't think libertarians tend to vote for authoritarians

I would disagree.
