Mark Harris figures it out - we're all an "infection" and he wants none of it. Reading his posting brought to mind an old classic Star Trek episode. Now we know what progressive Episcopalians think of us - we're infecting the church. And it's all the missionaries fault.
LATER: The term "coup d’eglise" has a rather interesting connotation. A takeoff on "coup d’etat" it is often used to denote a conspiracy of international proportions, usually from the Left (and often focuses on the usual conspiracy targets, you know who they are). It's TinFoil Hat Time. But me, I'd rather watch old episodes of Star Trek.
