Lockdowns are only a temporary solution. The vaccine loses effectiveness after a while- and there was a new variant.
These solutions aren't perfect. There is the wonderful perfect godly solution of just letting everybody get infected: No negative side effects to that solution, if you don't care about millions of dead people. And there is no guarantee that that will stop the epidemic either, as people do get infected a second time. But hey, who cares about dead people anyhow?
Lockdowns are another "solution" that doesn't work.
All they do is kill economies, create ill health due to emotional isolation, make it impossible for the poor to pay their bills, buy groceries, and pay their rent. Ah, but who cares about the poor? Obviously you don't or you wouldn't advocate something so destructive to them.
Lockdowns have also proven to overwhelm children emotionally while scarring them for life. Ah, but who cares about the kids? Obviously not you, or you wouldn't be advocating things so destructive to kids.
All the "leaders" advocating lockdowns are the same people who have been lying through their teeth telling you the shots were the magic fix. Turns out that is a complete lie. And you're still believing that bunch of liars. You must be a very slow learner.
