I suppose the fallacy is where the attributes are irrelevant to the argument.

There's a somewhat related comment I'd seen recently which I've found useful:

Nota bene: a fallacious ad hominem only occurs when an accusation against the person serves as a premise to the conclusion. An attack upon that person as a further conclusion isn't fallacious and may, in fact, be morally mandatory.

That's not quite what I'm doing here: I'm leveraging the attack on credibility to discount further statements from ESR. But for numerous reasons of psychology and general reputation, if not a strict formal logic sense, there's a strong rationale to this.

Or: the narrator has been shown unreliable.

https://en.wikipedia.org/wiki/Credibility

Traditionally, modern, credibility has two key components: trustworthiness and expertise, which both have objective and subjective components. Trustworthiness is based more on subjective factors, but can include objective measurements such as established reliability.

> Ad homimen would be "people named Eric cannot be trusted".

Since you actually wrote this sentence 9 hours ago, it is safe to infer that you really don't know anything about logical fallacies or what you're talking about in general, since you can't possibly have learned all you need to know about them in 9 hours. Given this level of confidence in something that is both wrong and easily checked, why should we trust any of your claims at all?

Or... should we trust you? But not ESR? Would that not be hypocrisy?

"An Ad Hominem is a general category of fallacies in which a claim or argument is rejected on the basis of some irrelevant fact about the author of or the person presenting the claim or argument."

http://www.skepdic.com/adhominem.html

"Ad hominem is Latin for "to the man." The ad hominem fallacy occurs when one asserts that somebody's claim is wrong because of something about the person making the claim. The ad hominem fallacy is often confused with the legitimate provision of evidence that a person is not to be trusted. Calling into question the reliability of a witness is relevant when the issue is whether to trust the witness. It is irrelevant, however, to call into question the reliability or morality or anything else about a person when the issue is whether that person's reasons for making a claim are good enough reasons to support the claim."

"It is important to note that the label “ad hominem” is ambiguous, and that not every kind of ad hominem argument is fallacious. In one sense, an ad hominem argument is an argument in which you offer premises that you the arguer don’t accept, but which you know the listener does accept, in order to show that his position is incoherent (as in, for example, the Euthyphro dilemma). There is nothing wrong with this type of argument ad hominem."

"An ad hominem attack is not quite as weak as mere name-calling. It might actually carry some weight. For example, if a senator wrote an article saying senators' salaries should be increased, one could respond:

"Of course he would say that. He's a senator.

"This wouldn't refute the author's argument, but it may at least be relevant to the case."

ESR's claims about politics : ESR's claims about technology :: your claims about logical fallacies : your claims about ESR
