Religion forbids doubt.

Doubt is one of the prime factors in human education.

Without doubt, there is no skepticism.
Without doubt we do not question.
Without doubt, all ideas are permanent.

Take away doubt... purposely and systematically strip a child of the ability to question, to wonder, to see more than only one side of any question... allow that child only faith and belief and you create a slave to what that child is taught.

Too often this is religion, this is violence, this is racism, this is misogyny, this is hatred.

We must doubt everything, question everything, learn as much as we can, because only in education and scientific progression can we become more than just an overpopulated, albeit somewhat clever, species of mammal.

Religion forbids doubt.
