However, you're still assuming, a priori, that the Church is the principal and not the agent in this story. Your narrative puts the Church in the role of being the one trying to manipulate repression and psychological conflicts for the ends of power, when it seems just as likely that the Church is merely the tool of other political actors toward that end. In fact, the main scholarship of the left on this topic, in the works of people such as Foucault and Hannah Arendt among others, would put the church in the role of victim/tool of totalitarian tendencies of the modern capitalist, law-based state toward the ends you describe.
With your rhetorical skills, you can derive why you're wrong about the entire direction of your objections. Align culture with our nature.
