That pretty much sums it up.

There are two parties for a reason. One for each end of the human personality spectrum that catches most of the in-between as well. People can't accept that the vaccines are bad because they can't believe that a conspiracy could be that big. It's the same thing with politicians; they are convinced that somewhere there are good politicians that will stand up for the people. They can't accept that all politicians and governments are controlled by a group of powerful people.

I'll admit that I was surprised at how easily Trump managed to capture a huge fan base of zealots. Like your video said, there is no evidence you could show that would convince a Trump fan that he is just like all of the rest of the politicians.

Both Trump and Covid have been excellent examples at how easily humans can be controlled collectively.
