We've been mostly ignoring Tammerlin Drummond, the Oakland Tribune's twice-weekly opinion columnist whose pieces generally offer banal but harmless observations. Sure, newspapers are shrinking, and we occasionally wonder why any editor would dedicate such valuable real estate to growing such a meager crop. But mostly we just move on. Today's offering, however, is a little too much to bear. Did you know that some people can be mean and racist, especially when email and web comment functions give them anonymity? Sometimes they even write nasty letters to columnists and call them bad names. Weep for the nation, America!
