Now it is clear that a new faith, based on fear of the invisible and quite immune to reason, has all but taken over the country. And it turns out to be one of those faiths that doesn't have much tolerance for those who don't share it.

My guess is that about 85 per cent of the population now worship it and will continue to do so. The rest of us are, as each day goes by, a persecuted minority, forced to go along with beliefs we do not hold.

Its evangelists will not leave you and me alone, but constantly seek to force us to join. This is why I make such a fuss about the demand to make us all wear muzzles. This is not about health.

There is simply not enough evidence to compel us to do so. It is an attempt to force submission on Covid unbelievers.

That is why it spreads, despite the absence of any good case for it. In a creepy development, one of the most powerful scientific papers arguing against it, Why Face Masks Don't Work: A Revealing Review, last week suddenly vanished from its usual place on the internet (I still have a copy).

Scotland's tinpot despot, Nicola Sturgeon, now demands that muzzles are worn in shops, as well as on public transport, north of the border.
