I have updated this article to incorporate feedback I've received, and have a final draft ready.
SteveW: I'm actually in strong agreement with you that this is [still] way too long! But my own motive for doing this was to debunk some misrepresentations, not to win a writing contest. If I had ambitions of being a professional writer, I'd certainly put more time into tightening this up and making it more concise, but I lack an incentive to do so. As [I think] Abraham Lincoln once wrote, "I apologize for writing you such a long letter. I did not have time to write a shorter one."
