Switching gears a bit but also somewhat relevant to this conversation. Isn't it funny how the definition for terms commonly used in the past are now no longer politically correct? In the past or at least in the exposure I had the term "fruit loop" meant bonkers, out of your mind, crazy or nuts and it didn't mean crazy in the literal sense. Now it's picked up an entirely different meaning for most people. One term that my kids always give me funny looks on is the term thong. I grew up KNOWNG that thongs were a style of sandal(?), footwear mind you. Now it's almost exclusively used to describe an undergarment.
I sincerely believe that civilized people should be sensitive when speaking to or about people. I used the term handicapped in another post, many would now consider this term to be inappropriate. I mean no offense in using that term. The term that is more commonly accepted now is mentally challenged. This said, why does a word or phrase that I've known the definition for years need to change because someone else said it does? I'm not yet convinced that being PC is necessarily what it's cracked up to be. Polite, pleasant, sensitive, yes but PC well...
I think it's much easier for people to use good taste when they speak as opposed to being politically correct. The Internet, email and texting is kicking our butts when it comes to this issue. Reading someones written thoughts as opposed to seeing that person or at least hearing that person speak all to often results in two entirely different outcomes. Voice inflection is so important when conveying thoughts.
