We live in angry times. For evidence, turn on any news program. An awful lot of people, led by right-wing politicians and radio and TV entertainers, are angry at President Obama for trading five Taliban officials, who have been held for years without charge in Guantánamo, for an American soldier, Sgt. Bowe Bergdahl, who apparently walked away from his post after having a change of heart about the War in Afghanistan. The Right is apoplectic.
