I thought you might.I disagree.
Whether they are effective at all is another discussion.So masks are a good idea but people not using them properly is the issue?
Do the ones people usually wear prevent the passage of aerosols?
No I am not.That's exactly what you are doing. Giving credence to bits of a website you want to make your point but ignoring other bits you presumably don't agree with. I had the same thing yesterday, someone saying "it must be true" because it was Public Health Scotland. When asked if they agreed what else PHS said - no answer.
I am arguing with mask zealots about what they should be doing if they believe what they are demanding - like arguing with religious zealots who ignore some parts of their holy book; it doesn't mean I believe in any of it.
