This is the writing of a “Marxist” anti-vaxxer. They obviously (and somewhat reasonably) don’t listen to mainstream media, so it’s more difficult.
Lockdowns aren’t detrimental if done in a humane way, but people indoctrinated with liberal hyper-individualism don’t understand solidarity and the importance of community. China’s lockdowns were very effective, and had minima side effects since they went along with really strong community support and clearly defined metrics of when to restrict and open up. Other socialist countries fared very well too. In contrast to that, western governments told us to stay home and fend for ourselves.
Calling the vaccines experimental is simply ignorant.
It’s not particularly constructive to use the information we have today to criticise decisions made in 2020 or 2021. We can however use what we know now to prepare better for the next pandemic. In a lot of ways we got lucky with how mild Covid is, compared to something like MERS or Ebola. There are indeed a lot of lessons to be learned from Covid and the responses, but capitalist nations are beholden to capital, lives and health don’t matter, and all inconvenient lessons will be made to disappear.
