They are insane, anon. It's the Zombie Apocalypse, only the ravers still "barely" have the ability to use a keyboard. Good people who were tricked into the terrible mistake of allowing a stranger to jam death into a vein, are one thing. But those weak and crazed minds that were already on board with the entire dark side agenda, are indeed having ill mental effects from the thing, and are making the jump to full raver light speed.
The takeaway from some vids I have watched, is that the GO allows the thing to pass the blood/brain barrier, and spike proteins are now relentlessly degrading their neural networks. And hey, when a loser started from an already low mental capability, what chance to they have to make sense or even remain human?
