By comparing the high level of contempt and insult in remarks by both Clifford Will and Lewis Epstein with the more civilized citations you print from John Chappell, one can sense not only that the former two speak from a sense of power more than from true expertise, but also that they must feel insecure in their beliefs, to seek to defend them by such rude attacks.
