Again, you cited statistics related to ‘self-identification’ to support your argument by comparing various subtotals using those numbers. As an interested but not uncritical reader, I happened to notice that the numbers you gave for “Christians” of one kind or another added up to 60% of the population. That number of itself does not support your “post-Christian” argument. I do not say it negates your argument — don’t necessarily want to negate it — but given that you were using those very numbers to support your argument, that was a rather significant sum. The ‘realness’ or ‘trueness’ of people’s self-identifications and their political alignments are separate matters.

As for “Evangelicals and Conservative Catholics” “compromising” with “Trump,” unless you mean to say that you think they have compromised themselves as Christians in supporting President Trump, I don’t see it. He has validated them by words and actions. That so much of their agenda is his (and the Republican Party’s) agenda is not, to my mind, further evidence of a “post-Christian” nation. Indeed, I think the political ‘right’ seems to be drifting towards some form of ‘Christian Nationalism’ as a new ideology—perhaps even including some form of ‘Christian National Socialism’ for those who accept the new ideology (though probably not with ‘that word’ in the title).
