“I have as much authority as the Pope. I just don't have as many people who believe it.”
- George Carlin.
Cults are built on the power of belief and the more people who believe in a movement the more powerful it becomes.
If ten thousand cult worshipers claimed their leader walked on water, how would you go about convincing them otherwise, even if you had proof.
Look at Islam or Christianity or Judaism, they influence the world but they're all only built on the power of belief.
And you can equate religions and cults because the only difference between the two is time.
