One of the pleasures of running a popular blog is in reading the many interesting emails my readers send me, out of the blue, asking questions, suggesting new topics, sharing their ideas, correcting my typos, and sometimes even sending in something that I can publish. And one of the least pleasant aspects of running a popular blog is in reading emails sent in by idiots. The world is full of idiots. While most of them seem to be of the quiet, unobtrusive kind, who might quietly sit in a corner eating a pot of glue, there are also quite a few belligerent, vicious, willfully ignorant idiots who spontaneously go on attack and start defecating in my in-box. Usually I ignore them.
