Off topic.

Your argument was a childish non-sequitur misrepresentation of your quote-ee's position, and pointing that out is entirely on topic. Perhaps you should be blaming yourself for posting something so thin on the ground in terms of ideas that I could respond so easily in so few words.

Aren't you supposed to be setting an example - "mod"

Yes, and a part of that example is not indulging blatant idiocy when it rears its head.
