The petition reads:
"Children have the right to their own thoughts, including their thoughts on religion. Because of religious hegemony around the world, children are herded into temples, churches, and synagogues without their consent and forced to endure dogma and superstition. The decision to take up a religion or remain free of religion belongs to an adult mind fully aware of the consequences such a decision will have. Usurping the right of a child to remain free of religion until they are adults is unethical, no matter the motivation of a parent."
