Part of the trouble with Political Correctness (there is much more) is that it has to be enforced politically (artificially) since it apparently does not stand up even to ordinary reason. If it did correspond to reason, that would make it true, not just “correct”. (E.g., “You’re not allowed to say that … In fact, it just might be a hate crime!”)
So the way I see it, the implication is that the kind of people who invent and insist on P.C. usage know that it is false (contrary to right reason), so they have to change the terms of the discussion and back it up with artificial peer pressure (demanding recognition of a non-existent duty not to offend and the non-existent “right” not to be offended) and, on occasion, the force of “law”.
