Fauci is a lying POS who ought to be in prison. The rest of your post doesn't make a lot of sense. Nobody with any reasoning believes or has proposed that masking and social distancing can absolutely stop the flu or any other pandemic. They absolutely reduce the spread. How could they not? Further, even if the measures we have taken this past year could practically eliminate the flu, we couldn't do it. We shouldn't do it. Despite the possibility of saving thousands of lives, it wouldn't be worth it. Just look at the cost of what we have done this past year. It is still a question whether the lockdowns were worth it even for COVID, which is much more deadly than the flu. We may yet find that the long-term consequences of our societal reaction to COVID may have cost as many lives as it possibly saved.
That said, let's pretend for a moment that the low number of flu cases/deaths that have been reported this season is all fake news. Let's further pretend that it was actually a terribly bad flu season with 100K unreported flu deaths, which would be the highest number of U.S. flu deaths in over fifty years. Let's also pretend that all of those flu deaths were mistakenly (or deliberately) reported as COVID deaths. That still would leave over 400K deaths due to COVID. That is a huge number of deaths and indicative of the worst pandemic in this country in a hundred years since the Spanish flu pandemic after WWI. It utterly amazing that there are people still trying to minimize this virus and pandemic and acting like COVID is no worse than the flu.
There is no doubt that this pandemic has been politicized. There is no doubt that certain segments of our government have used the pandemic to try and control our citizens and deprive us of our essential liberties. We should fight against that, but that doesn't mean we have to bury our heads in the sand, lose our minds, and disconnect from reality. The virus is real. The pandemic is real.
