What this manifesto really reveals is that this guy is an untreated schizophrenic who no doubt tried to self medicate with illegal drugs especially marijuana. The demonic Democratic rants, especially the Trump hatred fed his paranoia. Such people are at the core of the Democratic party. Almost all have embraced neo pagan, hedonistic decadence. They use politics as primordial therapy.
The left is of their father satan.
Could be, but no evidence yet submitted.
Reminds me of a bookish person who only reads horror or dystopian novels. Or a nerd trying to be cool by smoking a joint ir taking whatever mind poison someone offers. You become tainted by what you immerse yourself in.
Could be an unhappy, naive person with an obsession with being needed, looking to gain attention by giving people what he thinks they want or need.
Before I pursued a doctorate in STEM profession, I was the charge nurse of a psychiatric unit. The many schizophrenic patients with whom I engaged would have been completely incapable of writing a manifesto or planning an assassination.
My assessment:
This man is not schizophrenic, even if his lawyers claim that he is.
