>trying to be nice.

As I understand this thread, that's not even the point. The issue is, do we have the right to impose our current standards of "nice" on, to borrow a phrase that seems particularly apt, "prior art"? To me, that is quite different from using PC-isms in personal speech from personal choice. I say "Native Americans", partly because it seems more accurate, and partly to avoid confusion with my own Indian (subcontinental) heritage. That doesn't mean I would want to edit a work of art or literature that referred to Indians, nor would I ever say that, as a kid, I played cowboys and Native Americans. What one does with regard to one's own usage of language is one thing, but this thread really seems to be more about the propriety or otherwise of bowdlerising creative works to fit current estimations of acceptably inoffensive speech.
