My theory is that he was an angry fucked up guy. The rest is rationalization and power.

(The first gives the anger form. The second turns an anonymous crank into a global threat. Consider all the people here who say different things yet seem to be always singing the same song. Consider what would happen if you gave the average angry fucked up guy a billion dollar budget, a giant propaganda machine and an army. Consider what would happen if a cute little mouse grew to the size of a skyscraper)

But you know what, get a few drinks into him in a bar and he was probably pretty chill.

A person is very very large, deep and complex.

A bunch of words, even words of great veracity, are just a tiny cartoon.

To judge a large deep complex thing by a tiny cartoon is absurd.

(Unless you really want to judge of course. But that's another matter)
