Please reread. I did not use "insult" and "ad hominem" as synonyms.
Speaking of "boss", Pope Francis called his Vatican employees “the leprosy of the papacy," an “ill body,” “lords of the manor superior to everyone and everything" and “people who insatiably seek to increase their power and to that end are capable of calumniating, defaming and discrediting others.” He has accused them of  “spiritual Alzheimer’s,” “existential schizophrenia,” “hypocrisy typical of the mediocre,” the “terrorism of gossip,” “progressive spiritual emptiness,” having a “lust for power,” being guilty of “careerism and opportunism,” and cliques that “enslave their members and become a cancer that threatens the harmony of the body.”
Not the kind of boss I'd want to have.
