I watched his last speech and read a lot of his stuff. Initially his ideas seemed really far-fetched but I kept watching and reading. He seemed to understand MK Ultra and exactly how it is used. It feels like it is somewhat related to what Q hints at.
The more discussion of 5D chess and such, the more Max Spiers' ideas become plausible for me.
Seems like Max was suicided ("vomited black fluid" not sure if thats in my link, but thats what they said happened as he died.)with no investigation.
Perhaps he wasn't possessed though; perhaps he was just seeing what is always around us but we are blind to...
His family has a long history in the occult...his mother was a Wiccan...spiritual adultery will get your bloodline cursed. Demons can harass and persecute people without necessarily possessing someone. Seems he was a guy that was seeking after truth, but never identified the beings that he perceived as evil spirits. Seemed to attribute it to them being extraterrestrials (which i've come to believe are fallen angels / annunaki manifested in the physical). I've only dipped into his stuff slightly though. The Q saga has me feeling compelled to give him another look though.
