N. Kristof via Mediabistro: Kristof Apologizes to Reader (TimesSelect via Donkey O.D.)Nicholas Kristof: A number of readers were offended by my Sunday column in which I cited a letter from a woman named Marguerite H. who told me that I shouldn't fuss over Darfur because we have so many problems at home. Basically, some readers thought I was mean, arrogant, mean, sanctimonious, mean, self-aggrandizing and, well, mean. ... I'm sorry, Marguerite. I didn't mean to pick on you.
