Yes, a counsel of perfection eta :)

Your actions seem admirable Father Steve - and I love the image of trying to unring a bell!

To go back to your original question:
I wouldn't go so far as to say that "Oriental" is one of them. Am I wrong?

I don't think it's as certain as right or wrong, but maybe just one of those difficult areas where we all need to periodically test our alertness to changing social mores reflected in the language, to avoid our individual usage being left stranded like jetsam at some previous high-water mark. As TEd showed, it's possible we get a real surprise now and again, and may have caused unnecessary offence in the interim.
