I am willing to bet that it has significantly more to do with narcissism and a religious-indoctrination-induced mental illness than it does stupidity.

There's a reason they've been attacking education for generations. There's a reason donnie gassed a bunch of protesters to hold a bible upside down in front of a church. Religion literally teaches you to disregard logic and "just have faith", from birth. The sooner people understand the real problem the sooner it can be resolved.
