You are actually seeing "science" play out in real life. Previous science showed that masks have no effect on viral transmission (sources available on request). We had no idea what effect telling the lay population to wear unregulated face coverings would have on transmission or deaths. Nor did we know what the effects would be of closing businesses, limiting gatherings, encouraging people to stay home, etc. Now, we have 9+ months of data, and it certainly does not support the conclusions you are apparently drawing.
Again, I know it's hard to challenge what you are being told. Objectively, look at the trends around the country and present a counter argument. I will gladly entertain it.
