Friendly Atheism

[John 6IX Breezy]

 But I suspect even this will trigger debates about what "sound" means ...

As it should; I disagree with labeling someone's beliefs as irrational based on intuition. It warrants proper criteria and measurements.

Why do you keep trying to change the goal post away from rational religious belief? We are not talking about what is considered medically irrational/delusional. Unless you want to discuss why some of the christian beliefs could fit the medical criteria. 

Phobias by definition are irrational fears. Just because we think (have a hypothesis for) the neuropsychology of the brain for phobias does not make phobias rational. You have no idea of what you're talking about.

I gave medical criteria because it is the closest thing I can think of to an objective measure, and because you agreed with Boru that brought up psychotic behavior.

And no, phobias are not irrational by definition. Irrational is not a criteria in the DSM 5. The closest criteria to irrational that the DSM offers is "The fear or anxiety is out of proportion to the actual danger posed by the specific object or situation and to the sociocultural context" (APA, 2013, p. 197).
