Cynicism

Cynicism was originally the philosophy of a group of ancient Greeks called the Cynics, led by Antisthenes... Despite the negative portrayal of cynics, there are some who would argue that such people are simply those who "refuse to look through rosy-tinted spectacles" and are not afraid to demolish popular misconceptions no matter how sacred they are considered by society. Cynics themselves tend to take this view, regarding themselves as enlightened Free Thinker-s, and their critics as deluded social pretenders who "bury their heads in the sand." http://www.wikipedia.org/wiki/Cynicism
