For me I took a while, as I was beguiled by progressive issues like ending the Vietnam war and Earth Day. Ann Rand never helped. Basically when I kept seeing both parties having WAY too much interest in things they had no right to know, and both parties never accomplishing issues that I felt were morally imperative, I looked around. Initially it was just the lesser evil (the two oligarchies and the Libertarians) but actually the advent of decentralized cryptocurrency gave me the first glimmer that the oppression could be lifted through a combination of potent action and community building. Still on my way to having my thoughts freer but looking forward to more and more freedom.
