Wow, the party of liberty. Except when you disagree with them. Then it's ok to threaten you, call you "inhuman rot," and drive you from your home. ( @kenwhite.bsky.social you may find this, ahem, interesting)
It wasn't taken over by people who don't understand it; they've always been like this. I mean, look at how many of the old guard turned themselves blue on colloidal silver.
Tons of crackpots, always have been. LP has been 5 weirdos that don't agree about anything in a trench coat pretending to be a party forever. But the left-libertarian subcategory has been almost completely driven out by anti-immigration gun nut types. Culminating in the Mises Caucus takeover.
The more communalist libertarians have been gone a long time. There used to be a large cosmopolitan contingent who were big on freedom of movement / immigration. But they've been chased out. It's been a decades long exclusion process.
