Pieter, and a lot of serious Christians, are looking beyond the limn of this world when saying this. It’s one of the follies that devils drive. There may not even BE a distinct human conspiracy to this effect. And hell does not care if there isn’t one. Hell is more clever than people and it’s egotism personified anyhow.
I don’t know, when I hear “mind control”, “sleeper”, and “New World Order”, those are bywords of quite particular conspiracy theorists. Not just a Christian who thinks the devil is out causing mayhem.
