So what if a governor referred to a massively fubar-ed endeavor such as Boston's Big Dig as a Tar Baby. Why are people offended? Why are people offended at the slightest verbal faux pas, then demanding of apologies and retractions and media statements and resignations and reparations and and and! When the Los Angeles Unified School District Superintendent compared the LA mayor's assertion that the district is poorly performing to propaganda about the Japanese during WWII, that was another unnecessary furor (totally intended).
Get over yourselves people. Whether you're Jap, Wop, Chink, Nigger, Slant-eyed scoundrel, or a tar baby, you are not so almighty important that the mere utterance of the slur means you have been mortally wounded and retribution is mandatory. Fuh thuh luvah Gawd, just laugh at the errant stupidity, remember the last time you suffered from foot in mouth disease, and then get down off your goddamn high horse before you break your legs!
