There is your first mistake. Science is the systematic study of the structure and behavior of the physical and natural world through observation, experimentation, and the testing of theories against the evidence obtained. It has nothing to do with "facts" or "truth", there is simply, "This is what we now know, and believe about this disease".
Scientific knowledge is ever evolving and changing, as events progress and resources evolve. When the virus first appeared, we knew NOTHING about it, or how to treat it. There wasn't even a test for the disease. The Chinese were not exactly in the treat and study business. Sick people were treated worse than criminals there.
The USA didn't follow Fauci's advice at all. And the White House rewrote all of the CDC press releases, even after appointing an unqualified Trump loyalist to head the CDC after the previous Director proved to be too "disloyal" to the President.
We locked down hard for the first 6 months. We cancelled fall fairs, kids sports, and all gatherings for two years. We never ran out of PPE, our hospitals were never overwhelmed, but it was a near thing in some of the cities. And our people didn't politicize the pandemic nor did they carry on about it all like we were living in a NAZI regime.
Every time we watched how YOU were behaving, vilifying Dr. Faucci, and acting like complete idiots over public health measures, we just shook our heads at how stupidly you behaved, and what it has cost you. Trump should be prosecuted for negligent homicide for his "leadership" in this crisis.
