He has published an extended essay, Missives of Appalling Idiocy and Envy Embarrassing to Behold,  in which he discusses the horrific Twitter attack on Dr. Tomas Hudlicky, Professor & Tier 1 Canada Research Chair in Chemistry, and the subsequent problems it caused for Hudlicky.

Peterson concludes with this warning to those in the hard sciences:
I have suspected for years that the STEM fields posed the most dangerous threat possible to the unopposed dominance of politically correct sociological idiocy over the entirety of the university environment, basing their claim to validity on recognition of something approximating a universally accessible objective reality. That claim is too powerful to go unchallenged in today's climate of moral self-flagellating among those, particularly common in the ranks of university administrators, who want all the advantages of the power high-ranking hierarchical positions provide, but none of the hypothetical moral baggage that are part and parcel of the prejudicial and patriarchal structure that gave rise to those positions. The proper solution? Continual apology for the sins of others who occupy equivalent or superior positions, conjoined with a willingness to damage the reputation of those miscreants, and to force them into an apologetic stance—or even to apologize for their own unearned privilege, as long as that does not result in any true sacrifice of power, income or authority. This is particular evident, in the stories I have related, in the case of the Brock University Provost.
