Hang on you’ve all got it wrong. I read something once the gist of it was:
This is a CULT. They send their people out in the world to show the victims how AWFUL the world is.
The leaders are not actually trying to save your soul or convert you, they dopn’t actually want you to join and start asking questions. The victims are being manipulated.
They knock on your door, you are rude to them. Or you talk about satan. Or you invite them in to see your Ouija board.
The victims come away with an impression that’s what the world is like, full of rude, awful satan worshippers who take glee in doing things (blood transfusions) that the victims have been brainwashed into believing is terrible.
This makes the victims turn inwards even more to the cult and the safe sanctuary it provides.
The victims don’t actually like or enjoy knocking on your door, they hate it.
Remember they are victims – be nice to them and they will see the outside world is actually nice and might break out of the cult.
