What you posted was against the HN guidelines not because it was an ad hominem but because it called names (&quot;you are clearly ignorant&quot;, &quot;naive almost to the point of being moronic&quot;). It&#x27;s particularly uncivil to say things like that and then add &quot;don&#x27;t take it as an attack on you&quot;, as if you hadn&#x27;t added to the problem.<p>You clearly have experience and knowledge. There was no need to make this personal. If someone is ignorant, show them that by responding factually and stop there. Don&#x27;t rub their face in it.
