They know what they are doing. In the years leading up to the Trump era, the Lord totally changed my worldview. Being too ill to do much else but watch the internet, I had the thousands of hours to spend learning that most don't. I shouldn't be surprised at how many people have been duped by all this. It does seem like a grand paranoid delusion. Which is part of the deception.
If you work full time, with a family, doing well, then i can understand how your being duped
It was during last years lockdown when i was forced to stay home that i learnt much of the truth cos i had time on my hands
