With Political Correctness, you analyze a word, reveal connotations that expose an unwanted origin or association, try to come up with a new word that does not have those connections, and then try to enforce the usage of the new word. All with the idea that the force of the old associations will no longer have a hold (manners and mores, which I agree with you about, don't have this goal). But the old forces and powers are perfectly capable of attaching themselves to the new words.

The struggle in repression is real, even if it's unconscious. The psychoanalyst asks to speak with FREE ASSOCIATION and the inability to do this in SPEECH is what reveals unconscious problems. Repression, though, is a STRATEGY that we most definitely sign-on to. It FEELS unjust to be asked to take responsibility for something we didn't INTEND to do, but that, unfortunately, is our task in life.
