Based on the people I've come across, it's largely part of a victim mentality they have. They believe that mandatory masks are used by the government to see who will be easily controlled. They believe that climate change is a government con to raise taxes that will go straight in the pockets of evil socialists. They believe that the government plans to exterminate white people under the Kalergi Plan. They're the real victims of oppression, you see, not anyone else.
Instead of viewing the government as incompetent, as many do, these people see it as so ultra-competent that it's capable of running a secret campaign, alongside every other world leader that isn't far-right, to commit genocide against them. They've got everyone fooled. Not them, though! They're the smart ones who see the world as it really is.
