Which faction would that be? I'm sure there's more than one to choose 
from. An example of what they've done that, in your opinion, justifies 
that description might also be helpful

described as one myself. It means those who are knowledgeable about what 
the standard allows and prohibits, both for programs and for 
implementations. I'm no sure why you'd consider them "worshippers" of 
UB; they are characterized as language lawyers because they know 
precisely when the behavior is or is not UB - but that says nothing 
about whether they approve of UB or not. They would still be language 
lawyers whether they approved of UB, or despised it.
