I'm not saying nobody has, but I don't think anybody can take seriously the idea that 57,000 died not because of Covid but because of lockdown. It's a nonsense: it rejects testimony from medical experts across the world, be they epidemiologists or frontline medical staff; it rejects statistical evidence of, say, deaths rising in line with confirmed cases; incidentally, it also rejects the evidence that, as fewer cases of Covid-19 are recorded in the UK, the death rate has also fallen back to normal levels.
I am not sure it is right to say that all of the 57,000 deaths are directly because of Covid-19 either, but it is clear that a bulk of them are.
Finally -- come on, ymb, you used to be better at arguments than some nonsense about Covid worship. What is wrong with you?
