This discussion reminds me of a quote from George Santayana, "Those who cannot learn from history are doomed to repeat it." Revisionist history, no matter how well intended will inevitably contribute to forgetting the mistakes of the past and with equal inevitability lead to making the same mistake again in the future.
When well intentioned persons seek to remove offensive labels like "#$!&" or "faggot" they are denying today's children the opportunity to learn that critical lesson as anything other than a social should. Unless there has been "real" learning of the "why" behind the change, society will soon forget and new damaging labels will appear. We are not born knowing the why and each generation must learn the reasons anew, which is the real value of books like Huckleberry Finn in their unexpurgated form.
