A few times, I have put up links to Yale professor Dr. Harvey Risch's research paper showing pretty definitively Hydroxychloroquine / zinc / azithromycin is anywhere from 75-84% effective in preventing what would have been Covid deaths and/or hospitalizations, and why Fauci, the CDC and Dr. Risch's critics were wrong in saying the drug combo didn't work.
To this date, he has absolutely refused to read it - even though I clicked on every link he put up on this subject. I never asked him to agree with Dr. Risch's research. I just wanted him to look at it. His refusal to read the paper is very odd...but in character with how you described him.
