I get that some people think they are amazing protection.
And others think they are useless.
Or simply not suitable for selves.
Some people want everyone to take every possible precaution.
Others do the bare minimum and don't care if who takes precautions.
But those things are true of every other thing we are supposed to be doing about stopping the virus, like not using public transport, WFH, Rule of 6, 1m+. What is it about masks specifically that gets people especially cranky?
Best I can guess is that it's very easy to say if someone is wearing or not, human beings are very oriented to faces so anything on the face seems very important, and ... I'm not sure what else.
Does it come down to our primate nature being fixated on faces?
