>I know it's common for Americans to assume everything their government does is a false-flag pretext for a fascist power grab
History does not support the most hyperbolic speculations, but it does support the idea that the USG files away at the base of lady liberty every time the public's back is turned. Remember the Patriot Act and 9-11?
It can be true for some cases, but not all cases. Closing businesses, stay at home orders and quarantines are good ideas and, I believe, necessary for the public good. I'm also willing to believe they're temporary measures, if for no other reason than a permanent state of police-enforced quarantine would destroy the country and do no one any good, least of all the government.
Nobody (serious) is suggesting that everything will be permanent. What's being suggested is that several smaller changes made during the crisis, especially the ones involving legislation, will never be un-done.
