We've come a long way, baby. The concept of political correctness has yielded some big benefits: being prejudiced is no longer PC. But there are some prejudices that remain and seem to be tolerated - maybe because they aren't recognized as such. And intolerance to fat is right there up at the top of the list. Witness a recent post by writer Maura Kelly in her blog, A Year of Living Flirtatiously, who felt comfortable enough revealing her revulsion of fat to put it up on women's magazine Marie Claire's website. She would not have done it had she thought that it would create much controversy.
