Good post, Hyde. I play low limits and cheap SNGs and see this too often. Usually I let the first comment or two slide. But more than that, and I post something like "If you're so great, why aren't you playing 20-40 and trying to win some real money?" And if I get a reply to that, I post "If you were really a poker genius, you wouldn't be pissing on the people who are building the pots you're trying to win." The second comment usually gets the a-hole to leave the table.
