Sue - I would never minimize Fauci's "cache". There's no doubt in my mind he has a ton of it. I would also agree that he's a subject matter expert with 55 years of gov't experience.
My beef with the guy (and I suspect I speak for many of his critics) is that his viewpoint is one-dimensional. It was all about Covid. There was never any accounting for the potential downsides or negative ramifications for his recommendations. And he certainly loves the limelight. He seems to have an insatiable desire for attention. For me, I question his motives when I see this behavior.
Just because you're the smartest guy in the room doesn't mean you're a good guy.
Of course his viewpoint was focused on COVID - he was the premier expert on pandemics serving in the role that anybody should expect would be focused on COVID! But still, every time I heard him deliver the list of established pandemic mitigation measures (masking, social distancing, vaccines when they became available, etc) I also heard him saying at the exact same time that the aim of those measures was to get the kids back to school ASAP, to get people back to work ASAP, to get the economy back up and running ASAP ... Whenever he talked about any aspect of the pandemic, he talked about what it would take to come out on the other side of it with as little damage done as possible. He literally *begged* us to consider how our actions might impact other people, for all the good it did.
He loves the limelight? What kind of criticism is that?! Again, he's serving in the appointed position from which any of us should have expected that all of the current administration's pandemic-related policies and recommendations and orders should/would be publicized! That's the role! It'd make as much sense to take him out of the spotlight as it would to take the POTUS' press sec out of the day-to-day spotlight! (And here I'm not referring to - or criticizing - any certain admin, any certain POTUS, any certain press sec. I'm just talking about the normal, established process.) Did he have a little fun with Brad Pitt portraying him on SNL? Of course he did! So would anybody. The guy was working like a dog night and day and you could see on his face the toll that the thought of a pandemic killing a million Americans was taking. He was entitled to a few minutes of fun courtesy of SNL or his staff singing Happy Birthday to him in the parking lot.
You didn't mention the nonsense about him being a flip-flop. Again, utter stupidity when the one thing you want from the scientific experts is for them to follow the data wherever it takes them, even if it takes them on a zigzag route at 95 miles an hour - which COVID-19's evolutions definitely did.
The criticisms against him made no sense to me when they started and haven't made any sense to me any day since. It was utter lunacy for us to allow the targeted campaign against him, for us to buy into it when it was so transparent an effort to deflect attention from real, impactful failures happening elsewhere. The fact that he stayed working at his post throughout the lunacy, including very real threats against him and his family, is all the proof of his "goodness" that's needed.
