For a long time now, many people who's religious values are deeply important to them have felt disrespected and looked down upon by "the left" (yes, I'm obviously painting with a broad brush here). In subtle and not-so-subtle ways, the elite left essentially said "you all are backwards and silly". And look, I'm an atheist who has felt acute harms from religion in some very specific ways, so I get it - a lot of times I believe that religion is backwards and silly. But Trump and MAGA came along and essentially said "you're not backwards and silly, you're the righteous ones, the ones who are condemning you are backwards and silly". And yes, Trump has been married 3 times, had an affair with a porn star while his wife was pregnant, values displays of material wealth above all else, etc. etc., so I struggle mightily many times to understand how a community that preached "family values" so stridently for my entire youth supports him now so unconditionally. But, IMO, it's because Trump really constantly drove home this message of "you should be proud, and the only people who should be ashamed are 'the other side'".
I know that may feel like a tangent, but I've seen the general dismissive tone of this article repeated so many times (e.g. in much reporting about the Chick-fil-a family) that it now feels easy to recognize.
