It seems to have remained civil thus far, hasn't it? If we shy away from debates -- even ones we've had many times -- then this would be a dull place, don'tcha think? If someone states something that I believe is fundamentally misleading, is it not important to offer my own viewpoint?

Don't get me wrong. I don't want to beat dead horses (or witness them being beaten) any more than the next guy, so I'm adopt JohnK's methodology: say my piece and move on.
