I suppose I should revise my statement; it's actually quite startlingly easy to critique doctrines based on faith and scriptural authority alone. The thing that prevents people from doing so in any measure significant enough to enact mass spiritual transformation is the threat of organized violence that might ensue due to people's cherished beliefs being disturbed.

Though I am increasingly aware of both the inability of purely faith-based doctrines and materialistic atheism/scientism to address the cultural and spiritual poverty of the modern era. Really makes me wish places like Japan didn't become morally broken from the turn of modernity, or India destituted economically and civilizationally over the last few centuries. Humanity needs to find a new vision for a spiritual modernity that is pluralistic and empirically testable!
