I believe responsible folks should weigh conditions and circumstances for mask wearing.
The problem is that self centered judgmental people falsely believe they are respondsible.
We are now dealing with the Delta variant and should be on a war footing again and wear masks indoors. Yes we had a brief breather but that is over now. You are not just protecting yourself and the elderly but also the young and children. Its doing our part.

Global Policy such as exporting the manufacture of vaccine will also slow the progress of variants since only 1% of poor nations are vaccinated.
