There are many reasons why I don't believe they offer protection, but the main reason is from something I witnessed earlier this month (I have written about this on another thread).
I'm a bird watcher and, on one very cold day, I visited a bird hide. Watching the birds, I became distracted by a plume of smoke coming from a woman in front of me. I thought she was smoking at first. It wasn't smoke, however, but air/water droplets from her mouth showing up as clouds of condensation. This plume of 'smoke' was coming from everybody's mouths in that hide, but what struck me most was the fact that she was wearing a face mask. And, believe me, her breath was billowing out. Not from gaps in the side of her mask, nor from the top or bottom, but straight through the centre of it. Even I was surprised. The mask was preventing nothing getting through, certainly not tiny covid particles, had she been affected by it. I wish I'd had something on me to film it.
You've heard all the more crude analogies such as you can still smell a fart if you're wearing a facemask; or the nicer ones, such as you can still smell perfume through a mask, or cigarette smoke. Well, if all these molecules can seep through masks, then so can smaller viruses. As has been said before, facemasks are about as useful as tennis nets against a sand storm.
And don't forget all these so called scientific experiments - not one of them for ethical reasons have been carried out on people - they've all been carried out in lab conditions and are in no way realistic representations of what happens when people wear masks. Even scientists have admitted they can't do 'proper' tests on people.
As an aside, I'm not anti-vacc, a Trump supporter, a murderer, selfish or stupid, all of which accusations have been levelled at me. I'm just stubbornly sticking to what I believe. And I believe facemasks have just been used as a political tool - it makes governments look like they're doing something. Facemasks are the one visible 'thing' they have to turn to.
Do you go ranting at people for not getting tested, or for not being vaccinated? No, of course you don't - because you don't know whether or not they have been tested or vaccinated - their status is not visible. Facemasks have taken on this huge importance in people's minds because they give the appearance of being safe, but they are no more safe than a paper tissue.
I'd love a scientist to be able to explain to me what I witnessed on that morning in the bird hide. Any scientists out there willing to try?
