Is New Ben Stiller Movie Insensitive To Disabled?

Ben Stiller’s new film Tropic Thunder is garnering some complaints from the differently abled who allege that the film “humiliates people with intellectual disabilities”, according to this BBC story. Mr. Stiller’s character uses the word “retard” several times during the film to refer to another character. Production company Dreamworks denies that the movie, which also stars Robert Downey, Jr., has any such motivation.
