It is a mish mash of thoughts indeed! His actions seem like those of an extreme sociopath with delusions of grandeur. If it was hate that drove him you think he would have enjoyed what he was doing. He seemed to enjoy more talking about the weaponry and its failures etc than carrying out some sort of hate fantasy. Maybe under some sort of control or handler or maybe just talked into this sh8t over a long period of time. I have not read it all as it seems boring, repetitious and self indulgent. ie. “how many excuses can I give myself to go and do this!?” Still the repetition could be what has been told to him over and over again in various ways. I wish I knew more but his writings seem to be two sided to give everyone a bit of a reason to point to the other side as inspiration. Wile he sits back and laughs I presume!
Hate is a personal thing. This shooting seemed to me to be more a political event.
I agree that this was part of a bigger movement.
I should have mentioned I think it was written some time ago. Well in advance of events.
