What is Political Correctness? It implies belonging to a particular social group. This social group enforces written or unwritten rules about the truth or non-truth of certain propositions. This social group claims that certain propositions, x1, x2, … xn, are true, while certain propositions y1, y2, …yn, are false. A person that claims that any x is false or that any y is true makes a Politically Incorrect statement. A person that always conforms to the idea that all x are true and all y are false is deemed Politically Correct.
Perhaps Political Correctness is inescapable since humans must belong to social groups.
