I do think libertarianism has some principles and concepts that are valuable, I would have even called myself libertarian-ish at certain points, but over the years it's fallen into a similar bucket as communism from my perspective.
It's an attractive system until you start introducing the people.
Things aren't just black and white and I wish people didn't feel like they had to pick teams. I lean towards liberalism/socialism when it comes to social issues but I lean more libertarian when it comes to economic issues.
And unfortunately it has been co-opted by the right, like so many other things. They claimed the banner, and fly the flag, while embodying none of the beliefs. If you say you're a libertarian in America, people automatically assume you're Alt-Right, despite the fact that Noam Chomsky is a libertarian, or more accurately a libertarian socialist, or an anarcho-syndicalist.
