The world’s greatest tyrants live within each of us. They are our egos, and they rule us with an iron fist. The two things egos hate most are change and to be said to be wrong. Once we have decided an issue, ego takes over insisting against all evidence to the contrary that the original position must be defended until death.
It all comes down to the fact that people don’t want to know, They want to believe. How else does one explain MAGA hats fanatical support for a serial liar so transparent that even a 7 years old can see right through him.
