Pretty substantial parts of it, absolutely. And not just American; though the American ones are a much closer and more pressing concern.
In a way I sympathize(not with a lot of the individuals, because they are just such assholes that you’d need someone more benevolent than I am to do so); but with the tendency to drift toward believing that certain things(whether they be more orthodoxy-focused, on the protestant side, or more orthopraxy focused, on the catholic one) are proof positive of salvation.
If you are doing christianity, with the self-sacrificial and human/divine mediating role of christ being absolutely essential, the logic behind salvation not actually being possible to deserve or earn; but requiring divine election, is fairly compelling; but honestly pretty grim(it did give rise to an interesting but rather depressing genre of journal/diary keeping, among people who acknowledge that grace cannot be detected but are desperately introspecting for signs that might possibly be of it). Given how badly people endure ongoing uncertainty the temptation to move from either the strict predestination position of “grace is literally undetectable; and can be as easily bestowed on the worst as withheld from the best since all fall immeasurably short of either deserving it or not needing it” or one of the intermediate “formally, grace is freely and undeservedly provided and can’t be directly detected; but acting like a good sort is a pretty good sign” to the theologically questionable (and often obnoxiously self-righteous) position that grace can be discerned by some combination of performative piety and you receiving temporal favors that others do not.
The same is true, to some extent, of the tendency toward downright Manichean flavors on the fire-and-brimstone side. Theologically dodgy, and often a refuge of assholes; but when the alternative is trying to wrap your head around things being as they are despite a benevolent god with no real obstacles to the exercise of his will…
