First, the only natural 'right' of any living thing is the right to try to live. Everything else we discuss is statutory and provided by our various concepts of 'civilized' cooperative behaviors.

Second, I disagree with "But it does me no injury", because lying to children about imaginary beings and cryptological methods of deception harms those children in the name of power mongering by aristocrats (God being the ultimate aristocrat on top of the pyramid schemes).

If we continue to allow humans to believe they are more important than their children's reality and resources, then we doom our own species in the long term.
