Although I agree that we are framing this thread in the context of the original article, this medical professional is presenting their (experienced) opinion, and GP is not discussing it and instead chooses to require some token criticism of the article. This doesn't seem charitable to someone presenting their professional opinion.
You're right, and akdor1154 already addressed this in the same breath:
> I don't think that level of dismissal is fair or respectful unless you accompany it with a relevant criticism of the research itself.
Emphasis mine.
