The fear of causing offence has led some advocates of political correctness to ban words such as black, bald and even short.
An example; Students' union toilet signs at the University of Manchester have recently had a PC makeover. They've been "de-gendered".
Temporary signs have made the "ladies" simply "toilets", while the "gents" have become "toilets with urinals".
Susannah Birkwood from Student Direct newspaper said: "The toilets have been provided for men who don't self identify as men and women who don't think of themselves as women.
"Whether or not this is political correctness gone mad.. because it certainly seems that way to some members of our student community."
But Jennie Killip from the students' union told the BBC: "If you were born female, still present quite feminine, but define as a man you should be able to go into the men's toilets - if that's how you define.
"You don't necessarily have had to have gender reassignment surgery, but you could just define yourself as a man, feel very masculine in yourself, feel that in fact being a woman is not who you are."
Political correctness is supposed to protect people's feelings - to make people feel included. But has it gone too far? Hindering communication, causing divisions in society? Or maybe the pre-PC days make you shudder?
