My good buddy is a die hard christian. He does not belive in evolution(one of those kinds). I did not know he had such strong convictions until one year after i started hanging with him. He did not push it on anyone, he went out of his way to stay out of religious conversations. One night I asked him a few questions on evolution, heaven and hell... He just cited bible references. "this is what i belive and thats it" were he closing arguments. When i offered him books/articles on evolution and homosexuality he just dismissed it. He had no intention of learing anything. Religion actually deterred his critical thinking. This lack of seeking for knowledge impedes humans development and is a mental disorder.
