Hah! Exactly. And the MOST hell and brimstone versions in many cases.
Often it's the very same people who are SO scornful of religion, mainly Christianity (and I'm very much not religious, so really no skin off my nose, but I've been noticing the same as you a lot lately) that are buying into this and other crap in the name of political tribalism.
Astonishing how many wholly irrational, non-factual, deeply problematic and actual or quasi-religious beliefs can be ignored, accepted, or their problems handwaved away or blind-spotted if you tell yourself, "Oh, I'm a sceptic and a liberal, I'm not into fantasy 'old man in the sky' nonsense like religious people are! AND I've been to university, AND I vote for social justice issues. Therefore, everything I think and believe must be rational, factual, moral, just and very intelligent, and everyone whose opinion differs from mine must be the opposite."
