I'm not arguing with anyone besides anyone who agrees with the piece. Whether or not it was the original poster's work or not, the article is full of so many assumptions and points worth refuting, it's only fair a contrarian should criticize it in the same venue in which it was posted.
If it gets someone else their jollies that I spent my time arguing against it, what do I care? I'm worried about the reader, who may be mislead by such a piece if not confronted with an opposing viewpoint. I'd not want someone to ever see this piece of drivel displayed without a rebuttal.
I'd say everyone's contribution was made in the same vein, even if different responders took issue with each other's outlooks.
