Similarly, the evidence for climate change is pretty much undeniable now and I can only assume that those pretending it doesn't exist are not honest actors.
But the lockdown scepticism I can kind of understand as it is more of a political issue - the cost/benefit of lockdown and depending on the type of lockdown, if it will even be effective.
It seems the usual rational decisions over medical intervention based on quality-adjusted life years etc. has been abandoned in favour of emotional arguments.
China showed us lockdowns can work, but these "lockdowns" we have now just seem to be political theatre with little effect on transmission. The politicians want to give the impression of doing something because actually effective measures like closing workplaces and schools would be too expensive/difficult.
