How about this, applicable to the Rawat Religion?:

The truths of religion are never so well understood as by those who have lost the power of reasoning.

Voltaire

Or...a bit harsh, maybe?

Man will never ge free until the last king is strangled with the entrails of the last priest.

Diderot

My personal favorite, also quite applicable to the Rawat religion:

With or without religion, you would have good people doing good things, and evil people doing evil things.  But for good people to do evil things, that takes religion.

Physicist Steven Weinberg

Okay, one more:

The Christian religion, as organized in its churches, has been and still is the principal enemy of moral progress in the world.

Bertrand Russell
