People who believe in invisible, imaginary friends that live in the sky, control the cosmic fates, and generally rule over the destiny of every living, breathing thing on this planet and the next, shouldn't be allowed to breed. Proof of concept, history in its entirety, including "biblical history". The last couple millenia, sans the more recent centuries, were awful, terrible places and times to exist because of religion. The war and death, bigotry, all around destructive, polarizing nature of organized religion, far outweighs any possible, positive aspect. Only the last hundred or so years of human existence could even be confused with anything mildy resembling prosperity, and decent quality of life for the non-extremely wealthy. In direct correlation with the acceptance of science as a cornerstone of society.
