Moralism is historically one of America’s great defects. Moralism is intolerant of ambiguity; it perceives reality in extreme terms of good and evil and regards more sophisticated judgments as soft and unworthy. The temptation to moralize is strong; it is emotionally satisfying to have enemies rather than problems, to seek out culprits rather than flaws in the system. God knows it is emotionally satisfying to be righteous with that righteousness that nourishes itself on the blood of sinners. But God also knows that what is emotionally satisfying can be spiritually devastating.
