My mom marched with Operation Rescue during the summer that culminated in the bombing of an abortion clinic, and later the execution of the Dr that ran the clinic, in his own church, during service, while he was collecting offerings as an usher.
I know in painful depth every detail of how these people think.
It is not nuanced on their side. They outright reject empirical facts. They believe the earth is only 6000 years old, that the dinosaurs died in Noah's flood, and that evolution is a myth, not the central mechanism of all biology.
They do not care about the facts other than pattern matching them as rhetorical thought ending cliches.
They believe because they had an imaginary conversation in their head once, they are now born again, and have a private telepathic phone line to absolute truth. When they feel certain about something, it's the will of god revealed to them through the holy spirit. When other people express opposing certainty, it's because they have been tricked by the devil.
There is no good faith debate on the basis of facts or nuance with these people. You could spend years refuting every single thing they believe on a factual basis beyond any nuance or doubt, and they will blink, look at you, and then say something like "I know what's true in my heart of hearts."
Every single detail of how they talk about this and the actions they take make clear their actual grievance is regulating women's sexual behavior outside of their theocratic conception of marriage.
There is no need to defend these people as some sort of morally principled people confused by the underlying nuances. They are no where near that intellectually honest on the subject.
