As I tried to show in my previous note, the key point about _ad hominem_ is that it's about relevance, not just about the person. Suppose Andrew offers testimony that he saw Green Humpty Dumpty on the wall this morning, and says it explains the green stain on the wall. John says, "Andrew is a liar, because I have this secret letter from him that I intercepted and that says he used green paint in his graffiti on that wall; and also, I have this video capture from the period in question that shows the wall with no Humpty Dumpty on it, but shows Andrew painting the wall," that is not an _ad hominem_ no matter how it impugns Andrew's integrity. The counter-argument is directly relevant to testing the truth of the testimony, and therefore to undermining Andrew's conclusion. The term "_ad hominem_" is not a four-dollar way to say "makes me feel bad". It is a particular kind of fallacy in which the fallacious argument attacks the person speaking instead of the propositions in question. Saying, "John Sullivan is bald; you shouldn't believe his hair tips," is a fallacy, because my father's manifest baldness is just not related to whether his hair tips would be good for you. (As it happens, they wouldn't be. But his baldness is not the reason you should think that. There are successful bald hairdressers.) Whether a given bad argument is an _ad hominem_ or an appeal to popularity or a (phony) appeal to authority -- or even a circular argument ("begging the question") -- is just about the least interesting question I can think to answer. The issue when we are having these kinds of discussion is whether a given argument is a good one, and part of that evaluation has to be relevance, but getting the classification just so is only fun for students of rhetoric. All of that is, as John says elsewhere, also unrelated to whether we are creating a chilly environment, harassing people, or welcoming people into our standards-making activities. I can -- and I bet you can too -- construct a perfectly valid, relevant, and devastating argument that is delivered in such a way as to wound the person whose argument I am attacking. And I can produce -- I bet you can too -- an argument that is lousy, but that makes everyone in the room feel warm and fuzzy. These issues are very loosely coupled to whether something is an _ad hominem_. I think we ought to focus less on the classification of boorish or ill-reasoned utterances and much more on the quality of the reasoning and the openness of the presentation.
