I take it that Common Core, is the same thing as Common Purpose we have had in my country? First implemented as a charity in the mid 1980's by a far left woman? Infiltrated everywhere, police, schools, university etc. As for the masks, no research says they do any real job in stopping a virus, the makers of the N95 even say so on the website. Also the droplet size only filters down to 0.3 micron, the virus starts approx 0.16 micron! The exhale breathe is also not filtered. Health and safety regs would mean you are closely monitored for CO2 levels. The cloth masks do almost nothing, in fact most people fiddle with them, a lot I've seen don't even cover their nose! Oh and a virus will also enter via the eyes, so in essence a mask does zero in this case!
