A thought experiment: imagine sticking every American who has ever professed a strongly held belief about, say, climate change into one giant room. I can imagine they would number in the tens of millions, so it'd have to be a REALLY big room. Now imagine a mind reading device that can identify everybody in the room whose interest in the issue does not stem from a genuine desire to strike a balance between human welfare and ecological welfare. Now, kick all those people out of the room. How many people are still left?
Now imagine a different room where we stick every American who has ever professed a strong belief in Christianity. Now kick everybody out except the ones who have really committed themselves to following the teachings of Jesus Christ, every single day. Same thing happens as with climate change -- most people who hold a strong political or religious opinion don't actually care about the subject all that deeply. They think they do. They'll tell you that they do. They'll probably even get aggressive if you suggest that they don't actually care about the thing they're so passionate about. Behold, tribalism.
All that to say, if rational Christians are tired of evangelicals, it's long past time for them to fight back. Publicly. Rational Christians should be demanding that the IRS audit whether megachurch empires are abusing their tax exempt status. Only Christians get to raise this issue, because anyone else would feed the persecution narrative that's radicalizing the evangelicals. Rational Christians, on the other hand, can do a sort of jiu-jitsu takedown move and actually flip the persecution narrative inside out -- they can say, "hey, 700 Club and TBN, YOU'RE the ones attacking Christianity," and get people to listen.
