@matrix It's difficult to watch Dave when he gets like that. The claim that Christianity was essential in developing Western civilizations might hold water in a universe where the Dark Ages hadn't occurred.
I feel similarly irate when he complains that sports are "distracting people from the real issues." I don't even watch sports and I still find this attitude condescending, if not downright totalitarian. He seems to want everyone's attention to be directed at only the things he deems important.
