'''Political correctness''' or '''P.C.''' most commonly refers to the alteration of ones choice of words in order to avoid offending any group of people. More specifically, groups which (or whose putative "leaders" or other activists) claim some status as "[[systemically oppressed]]" will periodically attempt to change the terms by which they are referred to and demand that society as a whole change its usage of words as well. More generally, political correctness can refer to a broad range of lifestyle choices which fall into the realm of a political correctness movement aimed at changing (or expressing ones opposition to) [[Western culture]] as a whole.
An example of political correctness is the changing terminology used to described handicapped people. In the past the term "crippled" was perfectly acceptable and not considered offensive. At some point, somebody decided "crippled" was degrading and the preferred term changed to "handicapped". This, too, was eventually deemed offensive and "disabled" became the preferred term. Today, "disabled" is now considered degrading and "differently abled" and "physically challenged" are now the politically correct terms. The same can be said for the changing uses of terms for Black Americans: "Negro" and "colored", once perfectly acceptable terms, were declared degrading and offensive by some activists during the 1970s and "Afro-American" and "Black" came into use, which in turn gave way to "[[African Americans|African-American]]", and in broader usage, "people of color".
