Emergency room doctor & poisoning specialist here to say that masks do not reduce oxygen or cause poisoning and have not led to ER visits.
If people could get over their selfishness and ignorance and wear masks in public there is a very high likelihood we could actually reduce the number of people with respiratory issues, low oxygen saturations, and emergency room visits for the same.
The randos arguing with this know they are just proving the point about ignorance, right?

Also, if you think a scrap of cloth covering part of your body is âoppressionâ then pls move to a nudist colony or stand down from your nonsense. (Nothing against nudists - I just think the Venn Diagram of âmasks are oppressionâ & ânudism should be illegalâ is probably a circle.)
