On the other hand, anger directed toward others, while ineffective in eliminating the evil in them, corrupts the one cultivating it, no matter how noble his intentions, thus adding evil to evil. Anger directed at others, no matter how righteously intended, is to be rejected. We must, I believe, start taking Cassian's warning more seriously. Rarely a day goes by when I do not read, either on the Internet or in print, a piece aimed at combating a perceived error afoot in the world. In righteous zeal for establishing what ought to be, one finds it is so much easier to deprecate opponents by depicting them with as little nuance as possible.
Anger has no time for detail.
This is simplism taken a step further. Angry commentators usually understand their opponents much better than they let on. They know that if those opponents are depicted with accuracy, there has to be at least some sympathy for their position. Take the least appealing aspects of the opposing stance and exaggerate them while minimizing the aspects that might win the most sympathy. What better way to stoke the fires of anger than to depict one's opponents as the saboteurs of a better time, when things were more like they ought to be.
