That wasn't a personal attack. It was a statement of fact based on the obvious misinformation within their post (which was worse pre-edit, by the way).

If someone said "the moon is made of cheese" and someone replies "you don't understand what the moon is made of" that isn't a person attack, since it was directed at their argument not their character.

If I had called them names, broadly questioned their intelligence, accused them of bias, and so on those are all personal attacks. Poking their argument with "you don't understand the topic" is none of the above and not even in the same ballpark.

It was personal and its presence at the start of your comment was obviously abrasive. For our purposes that counts as a personal attack. It wasn't egregious, but (a) this kind of subtle nastiness toxifies the environment here, and (b) it marred your otherwise fine comment.

"It was a statement of fact", if true, is beside the point. Facts are often used as ammunition for gratuitous jabs. Indeed, they make the best such ammunition, because then one can say "I'm just stating facts." But it's the gratuitous jab that's the problem.

Please no personal attacks.
