It only takes courage for those who live in areas that are indoctrinated with dense religious ideology's who will suffer consequences for their actions. For most in the western world, it is not such a hard thing to identify oneself with.

edit: original response claimed it took courage to doubt the existence of a creator. It has since edited out to claim it simply takes intellectual curiosity. I would argue that the same intellectual curiosity could have the end result of someone having a belief in a singular creator of reality.
