Masks don't protect anyone and only add to waste. If you don't have simptoms you cannot infect anyone.
I don't bother with masks, just keep my distance. Nobody said anything to me in a shop so far.
Lunar567, this post, and all your subsequent posts, suggest to me and PPs that you have got the wrong end of the stick. I am really sorry to hear this. Is it comfortable or usual for you to not believe the things you hear or read by reputable scientists and be in a different position to the vast majority of the general public? If so, maybe what I and other posters say won't make any difference. But please allow me the courtesy of a chance to try?
First, the evidence you posted. Three papers, one evidence-based and two opinions (extreme minority opinions, and not by scientists, but fall in the category of conspiracy theories). As another PP pointed out, you have misinterpreted the evidence based one. The authors actually updated their original 2015 study that you linked to, to lessen the chance of it being misinterpreted. The takeaway is this "cloth masks should not be recommended for HCWs, particularly in high-risk situations" which as a PP pointed out, is not the case for the general public. We aren't health care workers in high-risk situations and the comparison made in that study was in 2015 clinical situations not at all relevant to cloth mask wearing by the general public. Even if you want to believe that, and certainly it does seem cloth is less effective than surgical (less effective is not the same as useless), why would you not want to protect others by wearing a mask? Do you usually live your life that way, ignoring others' well being?
I am sorry about your friend's 80-year old mum. But 80-year olds who can't wear masks, like many others, are exempted (and should be).
Healthy people surely can put a mask on, even if they don't agree it's a perfect solution, it's only a bit of inconvenience compared to the horrible situation some face, which is the 80-year old catching COVID and dying... or worse?
Please can you consider that maybe what you thought was evidence is not evidence?
May be this very balanced piece will help. the author, Trish Greenhalgh , is an extremely well respected (and no-nonsense) expert:
