Hello! I'm not after a scrap either! :) Gawd, no.

It's indisputable that covering your nose and mouth will stop many potentially infected droplets passing from person to person in an everyday environment, be it covid, flu or whatever.

It's also a known fact that some people may be asymptomatic carriers of the disease.

With that in mind, the quote that I tried to remember in my previous post is suggesting that anyone who is able to wear a mask that refuses to do so is unnecessarily potentially putting themselves and others at risk.

As some people are especially susceptible to the symptoms of covid, and with upwards of 820,000 people (and counting :( ) worldwide who have died from it, that susceptibility is not worth the gamble.

So my understanding of the quote is: There are those among us who are refusing to wear mass. We're only being asked to wear a mask for the 20 minutes or so that we're in an enclosed, populated space, and that - combined with other precautions, such as social distancing, washing our hands and disinfecting - may be enough to save someone's life by stemming the spread of covid.

And that, to me, doesn't seem unreasonable. :)

"is it ‘knowledge’ or belief?"

I have the knowledge not wearing a mask could harm others or I have a belief not wearing a mask will harrm others. Doesn't matter which.

If one has the knowledge it doesn't or a belief it doesn't (it doesn't matter which), one is mistaken and will harm others.
