Grey's Anatomy loudmouth Isaiah Washington did himself so much more harm than good by declaring backstage at the Golden Globes that he never called gay costar T.R. Knight the F-word. Not long after Knight went on Ellen to call his cast mate out as a liar, GLAAD issued a statement explaining that when Washington "uses this kind of anti-gay slur - whether on set or in front of the press - it does more than create a hostile [work] environment. It also feeds a climate of hatred and intolerance that contributes to putting [the gay] community in harm's way. Tragically, this sometimes can be the last word people hear before they're attacked, beaten and possibly even killed." In other words, Isaiah: open your mind, and not your mouth.
