What if you have no "base ideology"? Not everyone is brainwashed from birth, you know.
Anyone who has ideas about liberalism and conservatism has an ideology.
That's what I've been saying. Extremism isn't crazy or irrational. It's based on their religous texts and external pressures like corruption and the presence of unbelievers in your country.
Apparently it is also based on independent thinking. Perhaps we should all abandon independent thought? Just in case?
