I don't think they will make a difference even in America but I can at least see the rationale for them there. Here - utterly pointless.
^ a lot of non-zealots are taking the 'but it's worth a try, they can't do any harm' line ... I completely disagree - they do cause harm - particularly when forced on people - not least because they stop people doing the stuff that does actually help - washing their hands, not touching their faces & keeping their distance. I don't want to get ill because other people have adopted the magical thinking approach to infection control "... the mask will keep us all safe."
(fucked off today because I heard the classic woke kids digging into a shared tub of pringles & passing bottle around ... all apparently fine as long as you 'wear a fucking mask' - depressing)
Anyway, after my adventure with the vaccination, I took the children to our local posh town after dropping dd at work. It was lovely. Happy smiley people, flower pots & flags everywhere. Just nice & normal & busy. So different to home town - that's all black & yellow tape, spray painted 2m warnings, lunatic one way systems, glowering PCSOs & awful shouty women in masks guarding shop entrances. I know where I won't be going again anytime soon.
