I think it's extremely likely he developed a narrative that he couldn't then think outside of, and trapped himself in a mental cage.
Everything became a self-fulfilling prophecy, rationalising and realising what he already thought.
CTards do this all the time.
This guy was a full blown CTard, but certainly not along traditional modern lines lol - he wasn't influenced massively by memes, for example.
But I'd love to know what happened to make his views so extreme and personal that he felt he had to retaliate.
I think we can all see that what some of the things he say have truth in them, but why the unhinged response?
