When is a Religious Belief Delusional?

[SteveII]

There is no restriction on delusions that they cannot be shared with others: (from Marriam-Webster)

Definition of delusion

1 a : something that is falsely or delusively believed or propagated

• under the delusion that they will finish on schedule
  

• delusions of grandeur
  

b psychology : a persistent false psychotic belief regarding the self or persons or objects outside the self that is maintained despite indisputable evidence to the contrary

• the delusion that someone was out to hurt him
  

; also : the abnormal state marked by such beliefs

-------------------

Does this apply to religions? At the very least, it applies to beliefs in supernatural deities that affect day-to-day lives of people. Combined with the confabulation (called apologetics) that is typical of religion (and delusions), it is hard to see a way that most religions are NOT delusional.

Note the bold. Please provide a list of the "indisputable evidence" that there is no God. Absence such a list, such a belief by definition is not a delusion. Note that this is not merely "in spite of no evidence". It is in the face of indisputable evidence to the contrary. 

Even worse for your position is that you cannot even adequately undercut the evidence that people rely on for the religious beliefs. Who's delusional again?
