"Do you believe in Jesus Christ's divinity?"
"Yes."
"So you believe the bible is the truth?"
"Yes."
"ALL of the Bible, right? Because if some parts aren't true, maybe the the Gospels aren't and therefore Jesus might not have done all the things that were said of him."
"Right."
"In fact, the Bible must be literal truth, right?"
"Yes."
"OK. I have one word for you: dinosaurs."
"Oh fuck."
It's all a matter of connecting yourself to a belief structure and tying yourself to the mast in the face of evidence supporting contrary positions. It's the logic process those use to support Trump no matter what. They cannot accept contrary evidence that might shift their beliefs because their beliefs are all they have to guide them through this life and if they're shaken they have no roadmap, and therefore, no hope.
