Lighten up folks, this thread has imparted little of consequence in the last X posts. So much sensitivity! It's like watching bruised egos in brownian motion. Or perhaps not brownian - too random. Why, we know by now that if Y says black, Z is bound to insist on white, and if G momentarily agrees, F is likely to take offence. All of which doesn't help the rest of us poor ignoramuses trying to decipher some crumbs of knowledge from what could have been an informative thread.
