The relevance is that I thought it was relevant. You obviously do not. Referring to the Secretary as "Secretary Rice," is an indication of respect, and that she is deserving of respect (Note: I'm not addressing the truth of whether she really is deserving of respect here.) particularly because it would be coming from the President of the United States. Referring to her as "Condi" reduces her to a "broad," or, probably in the eyes of the Islamic World, worse.

I suppose you could be right that some would view it as reducing her to a "broad" but IMO the vast majority in our country view it as a term of endearment.
As far as how the Islamic World views it, I think many treat and view their women as nothing more than slaves anyway and as Americans why should that be of any concern.
