I think my comment was a dissenting opinion, not a personal attack. Its troubling that such a comment would be considered crossing a line
Also, "for the love of God" is an internet snark trope which both signals and amplifies negativity. You can think of it as a minus sign, or perhaps a triple minus sign.
I would not classify this putdown as a "dissenting opinion" because if you take away the pejoratives and the signals of negative sentiment, there is little if any information left.
Accusing the author of introducing slop into the language by coining (or using) a new term is a criticism of the author's work, not the author himself.
It's akin to saying, "Your work has a negative side effect which I don't like." Which clearly would've been the nicer way to say it.
I know "personal attack" sounds pretty strong, but the closer one is to being the target of such an attack, the more it feels like that—and there's absolutely no need to make a point that way.
