I have no interest in arguing this; if you search the web you'll find enough discussions on the point without adding one more. I felt obligated to say something, if I didn't use enough qualifiers and weasel-wording to satisfy you I apologize... but my conscience is clear; now that you've been informed that there's room for doubt, please feel free to use them any way you care to. I wouldn't think of interfering with your informed choice.<br>
