I hate political correctness, but at least it curbs some of the garbage that spews from some people's voice. If we did not have political correctness words as nigger, faggot, spick, kraut, cracker, honkie, would still be used freely as if they are appropriate ways to speak.
However often times political correctness goes way over the top. Go on the internet and one can find numerous examples of political correctness gone mad! My favorite is the following story:
In 2007, Santa Clauses in Sydney, Australia, were banned from saying 'Ho Ho Ho'. Their employer, the recruitment firm Westaff (that supplies hundreds of Santas across Australia), allegedly told all trainees that 'ho ho ho' could frighten children, and be derogatory to women. Why ? Because 'Ho Ho Ho' is too close to the American (not Australian, mind you) slang for prostitute. Source: 11 Examples Of Political Correctness Gone Mad
