“Political correctness is America's newest form of intolerance, and it is especially pernicious because it comes disguised as tolerance. It presents itself as fairness, yet attempts to restrict and control people's language with strict codes and rigid rules. I'm not sure that's the way to fight discrimination. I'm not sure silencing people or forcing them to alter their speech is the best method for solving problems that go much deeper than speech.”

― George Carlin, When Will Jesus Bring the Pork Chops?

Nobody can be an example of tolerance that has a problem with formal or informal modes of communication. It will never be true or believable.
