If Christianity gets wiped off from the West, of course it's going to be replaced by "science, logic and reason", which brings us to what is going on in our world. No masks, no jabs, you're not part of the cult, you're a heretic!
Now you're seeing the world that the likes of Richard Dawkins, Christopher Hitchens, Sam Harris, Carl Benjamin, TJ Kincade, Vee and many other Youtube skeptics and atheists have been building for decades. Do you still want to live in this world where "science, logic and reason" replaced Christianity?
The problem is that they're not even living under the principles of "science, logic, and reason." They've just simply discarded one religion for another. Social justice may not have a god per se, but it still has all the hallmarks, like original sin, rules of morality, and excommunication. And as is very common, those who convert tend to become the biggest zealots of all.
Their religion also has deities. One of their gods is Fauci. Their devil? I guess pro-vaccine operation warp speed Trump is too obvious but nobody else comes to mind.
Black Panther is jesus and Wakanda is heaven with their wonderful St. Floyd.
