Why can't most Christians understand the need for separation of religion and govt?

[Cato]

State sanction and enforcement of doctrine is only desired and/or required if said doctrine is found unsatisfying in the marketplace of ideas. We again run into what was mentioned in another thread, intentionally fomented widespread ignorance among the Christian masses regarding the origin and basis of the Establishment Clause and its refined meaning interpreted by the courts. In short, zealots who would otherwise have us living in a theocracy keep pressing the notion that the ideas that gave birth to the U.S. were based on Christian tradition. The amusing part to me is their ignorance of the fact that they are the types for which the principle was adopted and enforced by other Chrisitans. The separation of church and state was expressly designed to keep different flavors of Jesus from fucking each other over.

History places on full display the abject bullshit foisted on a populous when any particular sect is fully in command of political power. Cries for tolerance are still heard, but they now emanate from the previous tormentors as those having just been tormented conveniently disavow any knowledge of the word tolerance. Christians not wielding any power that have been convinced to support theocracy quite simply have no understanding of what they're asking for.
