Engage with them? Sure, I'm all for that. But I don't see what there is to ally with these people on. If their views win out among American Christians, then American Christianity is dead. The "YEC or nothing" dichotomy, along with climate change denial, both need to be rejected wholesale.
I do think “alliance” is a misleading phrase there, and I misuse it. My apologies.
I meant to say that, among the fundamentalist crowd, John MacArthur displays a sort of intellect and capability that the rest of them don’t. I mean, we’re talking about a fundamentalist who’s displayed vast knowledge(and vocal criticism) of the Founding Fathers, who really has a cult like following that Graham and Jeffries lack.
