I think that using "Gentlemen" as a salutation is harmless, and
suggest that anyone who gets really uptight about it should look inward
rather than outward for the source of distress.
Well, Hank, of course you think it harmless--but, then, you ARE male
(presumably); Larisa Overmier is not. Nor am I, and I cannot see the
appropriateness of my being addressed as "Gentleman." It seems awfully
late in the epoch to be STILL explaining such basic concepts.
