We enlightened Protestants thank you from the bottom of our unconstrained little hearts.
But what happens when we ain't the majority here...
Well, even devoutly Catholic Ireland managed to capture a bit of America's rebellious streak, because it had been occupied by a foreign crown and had absolutely no nobles whatsoever.
In retrospect, my Catholic/Protestant Royal/Republican correlations might have been too simplistic. Maybe the key to the formation of Christian Republics lies simply in the absence of nobility.
