Sadly, it seems "retarded" is about to join "handicapped," "oriental," "Jew," "midget," "niggardly," and the other "politically incorrect" words we may no longer use.
All words in the English Language are hereby BANNED as each one is, somehow, offensive to someone, somewhere, at some time.
This message will self destruct after reading, so as not to perhaps bring a sense of anguish and offended outrage upon any (probably non-existent) innocent party reading this.
