I disagree. First, although ad hominems are all too common in debate, the use of a particularly insulting ad hominem like "moron" indicates a small mind. And secondly, the phrase "knock it off" implies a threat, an indication that reasoned debate is beyond the poster's ability, and so he must resort to imperatives.

Familiar with the phrase, "pack mentality?"
When the light is shined on them, they behave just like the democrats during the last election.
