[desu_]

It's not a fallacy fallacy since I point out one weakness in the article but do not assume the proposition is wrong for that reason. Actually, if you read my last paragraph, it's obvious that I even agree with the author's argument to some extent. I only attack him for making a boring claim more clickbaity through his credentials.

From my quick skimming, mostly apo questioned the credentials. Yes, you are using ad hominem against the one you accused (rightly of doing so).
