Expressive individualism — with its contempt for and protest against all hierarchies, communities, traditions, and customs — represents the logical conclusion and the ultimate extreme of the secularization of the Protestant religion. The Holy Trinity of original Protestantism, the Supreme Being of unitarianism, and the American nation of the American Creed have all been dethroned and replaced by the imperial self. The long declension of the Protestant Reformation has reached its end point in the Protestant Deformation. The Protestant Deformation is a Protestantism without God, a reformation against all forms.
Kurth’s point is that the modern governing ideologies represent a progressive secularization of Protestantism, which he calls the Protestant Deformation. Kurth is arguing that the Protestant Reformation created the modern world, and the Protestant Deformation has created the post-modern world.
I would argue the opposite: Protestantism is a modern attempt at understanding Christianity.
