Oh, I did not notice this is your "virgin post" ;). Welcome to the platform! A very decent first post, mate. If you got any question about steem, feel free to ask by replying to me.
Sure critical thinking is something that we libertarians advocate ourselves, still libertarianism is an ideology and some people sadly treat it as a doctrine instead of a guidance.
An Ideology is to me more of a summary of my political beliefs, but I know that many people just use ideology as people used religion before, they declare their founding fathers holy and their core positions untouchable.
Many people on Steem refer to themselves as anarcho capitalists btw.
