Religious indoctrination is child abuse. The victims learn how to be morons.

"Scientific education and religious education are incompatible. The clergy have ceased to interfere with education at the advanced state, with which I am directly concerned, but they have still got control of that of children. This means that the children have to learn about Adam and Noah instead of about Evolution; about David who killed Goliath, instead of Koch who killed cholera; about Christ's ascent into heaven instead of Montgolfier's and Wright's. Worse than that, they are taught that it is a virtue to accept statements without adequate evidence, which leaves them a prey to quacks of every kind in later life, and makes it very difficult for them to accept the methods of thought which are successful in science."
