This would be my signature, but it's too long: "As long as it is understood that morality is a human construction influenced by human cultures, one can be more tolerant of other human belief systems, and thus other humans. But as soon as a group sets itself up as the final moral arbiter of other people's actions, especially when its members believe they have discovered absolute standards of right and wrong, it marks the beginning of the end of tolerance, and thus reason and rationality." - Michael Shermer, PhD
