John Scalzi, in his WHATEVER blog, recently had an entry entitled "Straight White Male: The Lowest Difficulty Setting There Is". It was a well thought out, clearly written piece, and it used an analogy that I thought was wonderful (even if not perfect). Unfortunately, many readers seemed to be from clue-free environments, and did NOT get the point. I have included a link here, so that others may go directly to the source and read it.
