The fact that this pandemic is being used as Trojan Horse to gain authoritarian control over the people, is so obvious at this point, that it's absurd that people still deny it.
The fact that people do, has to be (in large part) because of a mass psychological defense mechanism afflicting the vaxxed.
I don't think that they can face the reality that they're on the wrong side (the side ushering in totalitarianism), so they continue their support, regardless of how blatant the agenda presents itself.
