Given what you said, is it even worth having a conversation with someone who has gone out there to such an extent? If we are talking about science, where one can present evidence from which hypothesis can be re-verified by anyone, how do you deal with someone who just refuses to disconnect from their delusion for even a moment? As an atheist I have had some interesting conversations with what I would characterize as "intense believers". I have friends who are Born Again Christians. I have endured intense verbal poundings of all kinds at their hands. I even had a case where one of them was yelling and screaming at me in the middle of a parking lot at midnight because I was going on a business trip to Amsterdam the next day and he felt I needed to kneel down and accept Jesus that very minute or I would surely go to hell and condemn my whole family just for setting foot on that city. Nice guy and all, but holy crap! BTW, I have never done the opposite and tried to convince a believer to become an atheist. When do you think someone is so far gone that an attempt to engage based on reason is futile?
