If you can curate, censor, and control the flow of information, you can make people believe just about anything. This is why, pre internet, the propaganda was so effective, because the globalists had complete control of all avenues of information sharing (school, news, Hollywood). Only through cutting off the lies and exposure to the censored information, arguments, and discussion, free of the negative slant on it that's common among mainsteam media, and controlled opposition right wing media, can change someone's mind. That, and as the reality of the world conflicts with the lies, especially as the lies get more blatant and deadly to anyone that follows them, it will break more people from the propaganda spell.
