Well, I want to say "Thanks" to all who have shared their thoughts and experiences here. There are four "celtic" groups here, with overlapping memberships, and the little flap that started all of this has been the topic of a great deal of considered discussion within and among the groups. There are some who still don't get it, and likely never will, but there are many more who have come to appreciate the question of sensitivity, not because they think it is politically correct, but because they see it from a more basic perspective of courtesy and civility. All in all, it has actually been a positive ripple on the pond of tranquility. As is evident from the posts to this thread, there aren't really any bright lines that one can rely on. Thoughtful conversation seems to be the best medicine for soothing ruffled feathers when we do happen to cross one of those invisible lines.
