So you think masks are unnecessary.
But that's not the law, is it?
You can't have it both ways.
This is a straw man. Perhaps I should just leave you to argue amongst yourself 
I think masks probably make a small amount of difference and given the shitshow we find ourselves in, it's worth everyone wearing one if they are able to.
I don't believe masks make enough difference to justify all the nastiness and discrimination against people who are unable to wear one.
I am concerned that so many people have become so fixated on masks as the thing that will save us that they have lost track of where the bulk of the risk lies and which measures make the most difference.
I am concerned that the constant, rage-filled fixation on masks is fuelling the fire of the covid-deniers / anti-mask people / conspiracy theorists. These are a mixture of attention seekers and paranoid people. All this does is make the paranoid people more paranoid and gives the attention seekers more attention.
For these reasons I think it would have been much better if we had had a really decent public health campaign around face coverings instead of reaching straight for legislation. This might have been possible back in late spring/summer but it's not now because pretty much everywhere else has made them mandatory.
Given that masks have been made mandatory and there's no easy way back from that now, I'm quite happy with the law as it is, including the exemptions.
When posters come on and say 'In my country there are no exemptions' I can never work out what it is they are so proud of because there's never any evidence that it made any difference. It just makes me think their country has shat on disabled people for no good reason.
