Yeah, some are like that. But so are some of my fellow Christians. (And some Muslims, and probably some of just about any religious group you can pick out.)
This all goes back to the basic fact of human intellect: what drove its development was not so much that it enabled us to discover the truth, as that it enabled us to compete with each other for social position. The competition isn't usually about what we understand; it's about picking a side and claiming that we're superior because we picked the right side.
As a result, debates over religion on the Internet have a lot more in common with betting on predicted results of sports competitions than with seriously addressing the problems of human existence.
The challenge for individuals in primate societies is to be able to predict the behavior of others. [...] If, for example, individuals were able to monitor their own behavior, rather than merely operate as computerlike automatons, then they would develop a heuristic sense of what to do under certain circumstances. By extrapolation, they might then be able to predict the behavior of others under the same circumstances. This monitoring ability, which Humphrey calls an Inner Eye, is one definition of consciousness, and it would confer considerable evolutionary advantage in those individuals that possessed it.

“What you do in this world is a matter of no consequence,” returned my companion, bitterly. “The question is, what can you make people believe that you have done?”
