I realized after using this link yesterday its a psychological defense mechanism. Basically defense mechanisms: a guide on how to not feel bad.

This is how they resolve dissonant beliefs in some instances, its also why people wish mind bleach were real.

Also its a logical fallacy because it neglects how each version of religion is differently defined, and no one knows which one is real (except me, its none #Triggered )

So its also evidence of a misperception issue and unrelatability when a person produces this logical fallacy/mechanism.

Some examples:

You criticize christian fundamentalism: Oh those aren't true christians.
I criticize the old testament: They disown it.
Jesus practiced peace: I show them quotes on where he wasn't peaceful, they ignore it and say its out of context.

Defense mechanisms can happen anywhere and they are the same every time really. Denial, ignorance, bliss.

This is why there are fundamental logical errors with the religious unoriginal http://listverse.com/2009/04/13/10-christ-like-figures-who-pre-date-jesus/

Plus they do not have divined technology in rapid succession, the god acts contrary to their own stated plans and ideals. The probability is zero, the only way it could be right is through probability, and with potentially infinite variations of deities through probability one divided by infinite is literally effectively zero.

The only reason to believe is through logical fallacies and upbringing and impaired decision-making. And I am not trying to be rude, this is just the truth. I have yet to hear an argument aside from denial or case-study-like reasoning which is biased and fallible considering how much human psychological errors exist.
