When is a Religious Belief Delusional?

[brewer]

OP: To you most of the religious are not delusional because their beliefs and actions comply with the belief system. When the occasional believer is identified that does not comply with the belief system (i.e. Jim Jones/extreme example, Joseph Smith/less extreme) you then consider them delusional also.

Since atheists do not hold your belief system we have no choice to consider it anything other than delusion. You communicate with an invisible being (for which there is not concrete evidence) that created everything and watches over the creation all the while directing actions, proclaiming judgement's and imposing rewards/punishments. 

Religion is not considered delusional by most of society (at least in the US). That appears to be changing over time, even some beliefs within religions themselves.
