Wikipedia defines Political correctness (also politically correct or PC) as "a term used to describe language, or behavior, which is claimed to be calculated to provide a minimum of offense, particularly to the racial, cultural, or other identity groups being described. The concept is not exclusive to the English language. A text that conforms to the ideals of political correctness is said to be politically correct."
In this increasingly PC world, we are going to all need a handbook with lists of what is appropriate and what is not and what the alternatives are for the things that are not appropriate. (There is already a satirical version of this handbook.) We will have to carry it with us at all times and refer to it regularily because lawd knows, we don't want to offend anyone!
Are people's skins really that thin?
