Well thats the easiest way to brainwash people.
You write a religion... then you tell people they will go to hell if they don't believe. You also tell them that God wants them to believe in him without getting any proof. Then people "believe" in him just to be safe and teach their children to do the same thing. And bingo few thousand years later 1/3 of humans believe your lie.
So yes blind faith is the best way to brainwash people. |
