"I call it civilisational fragility if a nation depends so much on a single religion because any attempt to change amounts to controversy if not blasphemy."

The US is still a Protestant Christian nation, even for those who don't officially call themselves Protestant: they behave the same way due to cultural influences. Even the wokism isn't too different from evangelical Christianity if you think about it. Dogmatism, purity obsession, strongly us vs. them, etc.
