I try to avoid debates altogether after abandoning several because I wanted to call someone an egotistical fucktard. I have come to the conclusions that these debates accomplish nothing except skyrocketing blood-pressure. Choose your battles wisely like debates about teaching ID in schools. With meaningless debates, just take a deep breath and let them go.
Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own - Bertrand Russell
