Christians might point out that, at some level, an insistence upon doubt-based or evidence-based belief systems (at the expense of faith-based systems) constitutes it's own form of authoritarianism.

And at some level, they are correct.

But the thing is, evidence-based belief systems are always ultimately more democratic, and less authoritarian, than faith-based belief systems, in that they have democracy built into them, in the sense that they discourage claims that don't have democraticly / publicly available evidence.

Whereas faith-based belief systems necessarily have some prophetic or proprietary source of truth, which demands authority, and condemns democracy, when determining the veracity of truth claims.
