Well yes, religion teaches people to accept and believe, rather than seek the truth.
This has nothing to do with religion. It has to do with probable realities. Apparently you have never read any of Robert Anton Wilson's work or philosophy.
Well, no, I've not read his philosophy. I'm a believer in the best philosopher is yourself.
But I disagree that it has nothing to do with religion. People are brought into a world and surrounded by religion. They accept what they're told, and they're accepting something which is clearly not that true. It's just what people believe. These people are literally taught to ignore the truth, and accept whatever someone tells them to believe.
People will believe what is convenient for them. They've been taught to do this through religion, or potentially through other means, and they're adept at believing whatever they want to believe. When the truth comes along, they can avoid it with simplicity.
Imagine this. For many people accepting that religion is not true would be to accept that their family, their loved ones, lied to them, or that they're stupid and their family are stupid for simply accepting. So people get angry when they can't avoid the truth. I've seen it many times.
