I welcome comments from readers and I encourage debate. But I want to keep things civil. So as you write, please keep in mind I will not approve the publication of comments that are irrelevant, vulgar, profane, gratuitously derogatory or political. Nor can I approve comments that are advertisements in the guise of a comment or comments that come from phony email accounts. I reserve the right to edit a comment to conform to this policy if it makes an otherwise worthy point.
