My favourite part is after time and energy explaining error or fallacies in arguments and reasoning, they repeat them without a care, and then turn around and call you closed minded. Some even start throwing you refutation back like a child in a playground, “no you’re being irratuonal”…
You learn to just smile quietly to yourself. As you say, they have absolute truths from god, they are never going to be “fooled” by an atheist…who doesn’t even “know” that god is real.
