<p>The definition you cited is correct but I suspect you misinterpret its meaning.</p>
<p>Ad hominem isn’t simply something you throw around when someone makes an attack on character. It is something that refers to an attack on character <em>that is meant to refute another argument regardless of its merits.</em> </p>
<p>[Ad</a> hominem - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Ad_hominem]Ad”>Ad hominem - Wikipedia)</p>
<p>Anyways, none of the responses or claims about your character in this thread have been ad hominem. People are saying that your posts carry a sense of hostility and potential social harm to those who would follow your advice.</p>
