I believe English puritans were also in Holland and France for a while.

> Calvin himself ran a dystopian theocratic state\hellhole in Geneva yet hardly anyone references that when talking about conservativism in Switzerland.

I'm not familiar with Swiss politics, but if there's a significant Christian element to it, it seems like it would be pretty reasonable to wonder about whether the historical basis for this is related to Calvinism. If it's not significantly Christian, then it's not surprising it doesn't get mentioned.

> There was a significant generational backlash towards puritanism and a push towards pluralism/secularism by the late 1700s. IMHO Second/Third "Great Awakenings" had a much bigger impact than a handful of Puritans inhabiting New England in the 1600s.

Sure, but those those were backlashes themselves to the backlash to the secularism that you mentioned happened beforehand. I'm not saying that there weren't Puritan-like influences elsewhere, or that there were no other developments in between the Puritans and modern Christian conservatism in the US, but there's a clear historical tradition of Christian conservatism in US politics, so I don't know why you don't think it's unreasonable to recognize how that has influenced what we see today.

To explain at a higher level where I'm coming from: I don't see historical analysis as making claims about the state we're in today as being a deterministic outcome based on the events that happen in the past because that's not any more possible than predicting exactly what will happen in the future based on the knowledge we have today. The most we can do to explain why things are the way they are now is to look at what things in the past have influenced where we are today.
