I heard about the study and wondered if they controlled for BMI. This correlates with both severe COVID and diabetes. They didn't control for this or many other relevant factors.

I don't know this doctor or his reputation. He seems even keeled and rational. Has anyone seen a response to the types criticisms he's raising? They all seem legit to me.

Looking at his twitter this doctor is borderline antivax, definitely anti vaccination mandate, as well as is part of cadre of doctors selected to support imho an invalid herd immunity policy of letting everyone get Covid.
