Or to weaken an argument, or to draw attention away from an argument, or to
weaken future arguments...
However, although in this particular case the Ad Hominems constituted logical
fallacies, not all Ad Hominems are logical fallacies.
For example, if a person is a chronic liar, has a known history of lying, then
that can have a strong bearing on whether the person's claims -- technical or
about other persons -- should be seriously considered.
