As one who rarely has time to play on the internet, I'm not going to waste it watching stupid videos which don't prove anything. If people aren't acting, they could have mental disorders and still appear to be "channeling demons" or possessed. Until you first prove that demons actually exist, it's stupid to try to prove that demonic possession is a reality.
