Nice OP. I'm glad the apologists are here. Most of this is human nature; all of us have a tendency towards confirmation bias. It is in our evolutionary DNA. That's one of the best things about pursuing higher education, as it (should) program us so that confirmation bias becomes less pronounced.
But with or without higher education, if an individual makes up their minds to live an evidence based life and to stop, as much as possible, making decisions on nothing more than feelings, beliefs, personal thoughts, desires, all of which are supported solely be confirmationally biased information, all religions will quickly seem to be repulsive throwbacks to our evolutionary sojourn, deserving to be thrown on the ash heap of history.
Arguing that the Dark Lords are better than the Popes or that the dub religion is somehow preferable to other x-tian religions seems to most of us as a foreign concept born out of immaturity and a misplaced sense of hope. My aversion to the Dark Lords control is such that I would prefer being around people with tattoos and purple hair than the well groomed, deeply programmed drones in the KH. They make me want to projectile vomit.
Confirmation bias and being driven by our emotions and desires are the blinders we all wore. The apologists are here because they are 51/49 dubs; if they stay here that % will change as they take off the blinders.
