I haven't commented on this column by The New York Times' Nicholas Kristof because I've submitted a letter to the editor regarding it. The Times won't publish the letter if it's appeared anywhere else -- including the Web -- so I'm going to give them a few days to make a decision on publishing it. If they don't publish it, I'll post it here by the end of the week, but you can get the general gist of it from this post from last month.
