His 'modicum of expertise' amounts to him having read Cass Review that the SciAm article was critiquing, which was something the SciAm contributor had clearly not done. Since the Cass Review was saying "WPATH and AAP guidelines are flawed and here's why" and the SciAm response was "Cass Review doesn't comport with WPATH and AAP guidelines"

So yes, I'll consider the analysis of someone who has read the document in question, over the hack who didn't even read or get it and just wants to parrot the Progressive Dogma by denouncing everything they disagree with, using appeals to authority (WPATH and AAP).
