If you grow up in an echo chamber, libertarianism can seem like the best option. Growing up my understanding of things other than capitalism/status quo was "the cold war was a thing that happened". So like when I started to break away from my parents politics, I went under "libertarian" cuz my thoughts were, the government should leave you alone, and I didn't understand anything on the other side enough to genuinely agree or disagree with it. If you've heard of the Overton window, it's kinda like a personal Overton window, what is an "acceptable political option" to you. It's hard to break that shit, but it's possible, I can see how people get there, but there is a clear path out usually.
