Mr Cannataci, quoted in the link, is certainly correct about the process. In the past we had war-time emergencies and the result was not dictatorship following the end of the war. Still, some of the less offensive steps taken at that time were actually not repealed, so it's not as though there was no lasting consequence.
In the current crisis, it is worrisome, to say the least, that people are justifying substantial limitations on freedom by claiming that a pandemic is a
de facto war.
It isn't, but we see how easily a false analogy can be made, enforced, and...unfortunately...accepted by the public as a whole.
But there is still the question about
how much of a reduction in freedom the American people will or would tolerate. In the past, I'd have said "not much" or "not very quickly."
But in the Bernie/AOC era when state governors -- not the president but governors and even mayors -- are issuing commands left and right, ordering police to apprehend lone joggers, or to confiscate private property simply because the one giving the order who didn't need it yesterday today says "we need it," and that's supposed to be good enough as an explanation, I cannot agree any longer that the descent into authoritarianism is unlikely.
