First, a confession. I handled a recent comment on the blog badly. A reader wrote in with a question that I read as a political diatribe, and I dismissed it without taking the question itself seriously. I realized that my response was wrong and have since apologized, publicly, in the comment section of that post. I owe my readers, if I can respond at all, a thoughtful engagement with their issue, and I failed that standard. I will try to do better going forward.
