Are you agreeing with me, or not? Sending me that link without any other kind of comment, as if I were one of the few dozen people on the internet that are unfamiliar with the ad hominem fallacy, is a bit patronizing. My point is that attacking someone's argument by noting their poor academic track record is not ad hominem, it's a perfectly valid approach. Otherwise non-science people seeking to alter scientific consensus would have a trivial loophole to DoS the process.
