It didn't come off as an insult to me. Anyone saying C++ or Nim tends to result in a counter from pcwalton. He usually says similar things as he has a consistent stance. Countering such a stance before they speak is OK given you already know what it is. In in a moral sense anyway.

However, that he stopped in his own comment to bring it up and drop a counter says more about him than pcwalton. Shows a strong bias for and protectiveness of Nim while also disregarding the entire reliability or security aspects of the language. That's really something for a C++ alternative given its safety focus. ;)

Sure, and I can apologize for my wording in advance too! But I do stand by my opinion that he doesn't have to drop that in every single time Nim is mentioned. Evidently Go-people feel the same I noticed.
