Christianity; The World's most vile religion

[Sheldon]

Smart people holding irrational beliefs neither grants their irrational beliefs  credit for their intelligent ideas or vice versa

This hits the nail precisely on the head, all human beings are fallible evolved apes, even a genius who advances human knowledge exponentially can and will be wrong about something. I guess where science and religion separate, is that the methods of science are designed to reflect objective reality by removing as much subjective bias as is possible, whereas religions already have one core truth, and bend everything subjectively to fit that idea. Some of them even revel in the idea of subjective bias as a virtue, like religious faith. 

Whether one reads archaic claims for the supernatural literally or as allegory doesn't really change that distinction. Ultimately do you care more about the belief (religion), or more about whether that belief is true (science).
