Yeah, I suppose if you believe Christianity is/was the only thing holding civilization together, then adopting "Liberal hypocrisy" to fill the same role might make sense. Many people would disagree with the premise, though, by pointing to the Dark Ages and such. I don't really know what to think about this.

The Christian religion was adopted much earlier and by a much larger proportion of the population in the Eastern Roman Empire than in the Western Roman Empire. The former outlived the latter by over 1,000 years. Obviously, the degree of Christianization was not the only difference between Rome and Constantinople, but it is an important fact to keep in mind when reasoning about these sorts of things.
