1) He points out your cited expert's analysis is wrong.
2) So you presume he trusts everything Dr. Fauci says is correct
3) Now because he doesn't defend Dr. Fauci, you assume that makes your world view correct?
Even if Dr. Fauci is proven incorrect and incompetent. . . that doesn't prove you are right. Just like Bible bashing on the mission never proved anyone correct.
Also I would be doubting Professor Wittkowski before doubting Dr. Fauci, Dr. Fauci literally wrote the book on treating infections in the hospital. As the co-author of "Harrison's Principles of Internal Medicine" and the primary author on infectious disease, he is likely the most cited Infectious Disease specialist in every single state and hospital across America. Every Internal medicine program I know uses that book as their bible.
Plus professor Wittkowski's own quote "reducing disease severity, either by vaccination or by early treatment of complications, is the best strategy against a respiratory virus disease." Sadly we currently don't have either strategy, and are trying to prolong and reduce the total disease spread, and then will eventually have this option available.
