Argument: Pupils are unable to consent to school prayer
"The Case Against School Prayer". Freedom From Religion Foundation - "Public schools exist to educate, not to proselytize. Children in public schools are a captive audience. Making prayer an official part of the school day is coercive and invasive. What 5, 8, or 10-year-old could view prayers recited as part of class routine as "voluntary"? Religion is private, and schools are public, so it is appropriate that the two should not mix. To introduce religion in our public schools builds walls between children who may not have been aware of religious differences before."
