It doesn't matter if they were puritans and pious, the seed was there and it blossomed into what the US is today. Protestantism always runs counter to conservatism because it's a progressive theological stance that rejects historical tradition of Christianity. It's also always revolutionary, because it rejects Church authority and makes every person into "their own pope", so it's based on relativism and individualism.

Communism is an escalation of the Reformation but it's within the same revolutionary ethos and surprise, it's the jews again behind it. International jewry loves their revolutions especially when royal heads roll and newly democratic puppet governments fall in their hands. This is what happened in England in 1640, in France in 1790, in Russia in 1917 and Germany and the rest of the free world during the world wars.

This is not an excuse of RC because the Western Church started falling away centuries before Huss, Luther and Calvin. In a very big way, Rome started the process when they started adopting new heterodox doctrines and made a single man a head of the Church, when historically the Early Church was synodal.
