Proof and evidence will always equal Science

[Anomalocaris]

I suspect they are not the exception really.  they are much like many of the others in the reason for and manner of their belief.  Except they have a combination two other traits:
1.  They are not so secure in their own beliefs as to say ridiculous or not to someone intelligent, this is their belief.
2.  They have exaggerated notion of their own ability to obscure the ridiculousness of their belief with overblown word games when the ridiculousness is pointed out. 

if they had simply said it must be true because it is ridiculous, then at least it shows the conviction of faith.

I think they believe they're the exceptions, exceptional exceptions. And I know they're all about belief.

But I suspect they inwardly rely very much on the number of “unexceptional” believers to buttress to themselves why they should believe.  

they don’t think the ridiculousness of the common belief of the common believers makes the common belief ill founded.   the number of common believers very much contributes to their own belief.   they just think they are better at obscuring the ridiculousness of the very same common belief before any critical examiner than the common believer.    

which makes them not uncommon believers, just uncommonly unscrupulous advocates of the same ridiculous common belief.
