I used to be big into libertarianism, but kind of faded.

i am a cultural libertarian, but then I don't see how it can ever work.

I shy away from anybody calling themselves libertarian, since i think now they are ideologues and faux-intellectuals. I don't see how they are applicable to the real world, at least how society is in 2017.

It's also too theoretical. I try to compare to ideologies that started from small, and come up to prominence, like Marxism. To the average peasant Russian, it appealed a lot for obvious reasons. The same is true in a way of fascism, Italy and Germany at the time needed a strong hand.

Do people today need libertarianism? They don't. And it doesn't make them stupid. In a way, it makes libertarians stupid, since they don't know how to communicate or influence people.

It will take a radically different societal model or position for libertarianism to ever be valid.

Like there was some libertarian guy on Joe Rogan lately, who said it's the "best ideology ever devised". Like isn't this what ISIS believe? Or Marx? Or Hitler? Or Martin Luther? Or anybody else who has made a new set of principles?

This may seem unkind, but it wouldn't surprise me if most libertarians had some kind of autism. It may fit, considering they lack the ability to relate, have presumptive views on how people should understand stuff, and don't understand incentives or context. Hitler was evil, but he surely knew how to persuade, and how his ideology fit the given context.
