It may have been more lack of thinking than deliberate jerk-ness.

But that's nothing compared to our first book exchange. One of the guys got a Margaret Atwood book and I think it sort of freaked him out. He asked if anyone would take it and then opened to her picture and started making fun of her hair. Because, of course, skill and technical expertise (not to mention actually selling books!) is nothing compared to how pretty a woman looks. Ever since I have brought a book by a woman to every one of these exchanges.
