The author is talking about a learning experience he had regarding a deficiency he identified (being a jerk) in his own work (reviewing other coders' code). Meanwhile, your comment levies personal criticism toward him using pretty inflammatory language ("toxic," "sad," "asshole," "jerk," etc.), because of the way he responds to people who are learning. Interesting juxtaposition, that.
