Dear Jim, with all due respect, I disagree: Americhristianity never has "its best day" being "nothing more than Churchianity".  That's exactly what it wants you to think, and then dismiss it as "mere Churchianity" . No, Americhriatianity is a dangerous, anti-Christian, Gospel-betraying, dangerous cult masking itself as "church" (like Satan appearing in the guise of Light, Lucifer).  Americhristianity's Trinity is: the leader (German: Der Führer), the gun (law-and-order-or-else!), and the flag (draping the cross into invisibility - "the Other" shall die on it; it burns in black neighborhoods; it is not the Cross of Jesus Christ, nor is the flag the symbol of the US Flag and the values the Flag represents, but its vile usurpation).  I am serious.  A Dutch Jesuit, deceased several years now, who taught systematic theology in Chicago through many years, once stated that, should the RCC ever experience a schism again, it would take place in the USA.  His comment may turn out to be true...
