While I agree that the criticism "you're just trying to look smart" is misguided, it's a bit ironic that his response had the implication that "if I know this thing and you don't then you should be embarrassed [because I'm smarter/better than you]."

(I think that was the source of much of the objection to the comment, and the post makes no attempt to apologize for it, even if it was unintended.)
