UPDATED: I Do Moderate All Comments
I disallowed a comment just now. That's not something I like to do and, in fact, I have done so only very rarely. This comment by a regular stated that named individuals "need to die" and "should be put down."
I don't have any real rules for moderating comments, but I'm not gonna allow those types of comments.
UPDATE: Thanks to everyone for the support. I'll say it again: I feel a real sense of obligation to those who take the time to comment--and whose contributions add so much.
