That's the rub: these people think they are the most American, and you're not. I wonder whether they think of their patriotism in the same way they think of their born-again Christianity.
Born-agains believe that only the blood of Jesus can save you and and it's the only way you can go to heaven. Good works don't matter. In fact, born-agains deride the idea of people thinking that good works make a difference. Instead, they just profess that they are "saved", and once you profess this, you've punched your ticket to heaven, and only explicitly rejecting Christ, and nothing else, will forfeit that ticket. That's why Catholics fret about going to heaven and evangelicals don't: Catholics are constantly worried they'll end up in h-e-double toothpicks on some technicality they aren't aware of. Born-agains have no such fear.
Because of this, there is no incentive for born-agains to act morally or perform good acts because, as it relates to their salvation, doing so doesn't matter. They are already saved and going to heaven no matter what. I'm not saying that all born-agains see accepting Jesus as a welcome license to sin, although probably some do. And I would bet many try to become better people once they have been saved because they truly believe that is what Jesus expects of them now. But whether you continue to sin freely or try to avoid doing so, once you are sanctified in the blood of Jesus, your actions mean literally nothing to your afterlife status. This is how an entire town of born-agains could participate in or enjoy watching a hideous lynching on Saturday night, then comfortably go to church and praise Jesus the next morning, and not feel even the slightest pang of guilt. The way they act on a day-to-day basis doesn't factor into their salvation, so they can neatly compartmentalize those parts of their lives away from each other.
So I wonder whether they think of their patriotism in this same way, where all they have to do is profess their love of Trump, pledge allegiance to a flag, and sing Lee Greenwood songs, and that makes them a pristine patriot who cannot be besmirched. Then anything they say or do that appears to undermine the principles upon which America was founded and which has been shaped across more than two centuries doesn't matter. U.S. leaves NATO? Yes, please. Pull all support from Ukraine and let Russia have it? Of course, it's not our problem, and Russia is a better ally than those commie NATO nations anyway. Help Israel destroy Gaza and everything and everyone in it? We must, the Bible has foretold it. Suspend the Constitution? OK if Mr. Trump needs to. Eliminate future elections? Mr. Trump is in control so what do we even need elections for anymore? None of this ignites even the slightest pang of guilt in them, because they are patriots, and anything they do, say, or profess to believe doe snot factor into their level of patriotism. They have been saved. And that's all the counts.
I wonder whether this hypothesis holds any water? I'm guessing a few people here will be glad to tell me why it doesn't, or at least to pick something to whatabout me on.
