This column isn't taken to scolding very much, and aside from the occasional Tweet war, it doesn't have a temper. But having been steeped in the science of stigma , I've got to make an exception. This New York Daily News headline about a corrupt union boss , "PIGGY'S BANK," clearly, unambiguously, and undeniably connects his girth to his actions; the writers are playing off of, and reifying, the linkages between fat and excess and uncontrollable urges. And readers get it. I got it. I kind of laughed at the headline, and then felt ashamed of myself. We are so conditioned to accept without remorse the fact that we find fat funny.I don't know why Daniel Hughes, a Port Authority union leader who admitted stealing $500,000 to feed his gambling and sexual addictions, happens to be fat. I do know that his weight has nothing to do with the substance of the story, which is about his crime. It's very easy to write a lede that begins with "A roly-poly rip-off artist...," much like how the New York Post used to call Monica Lewinsky a "portly pepper-pot."
