If that is so, then there must have been an awful lot of Puritans.
I understand there were not so very many of them, and so, while a pleasant hypothesis, it may not be very true.
I see, actually, not much wrong with Puritanism. As long as their numbers do not go viral.
They were, though, outcasts, and many formed the basis of the New World, so perhaps there is some truth in your view, after all.
Political Correctness got its start in the New World. It was relatively unknown in Europe for a decade, or so, after its inception. Almost everybody knew, on some level, that it was insane, when it first became visible, which is all the more puzzling when one considers how fast it became the new secular Bible.
I suppose 'secular' is the key, here. The Puritans had the actual Bible, handed down over centuries, and based upon reverence for a transcendent God. Whereas the secular version appeared from nowhere, for no reason, with reverence for nothing but itself.
