"The Court also emphasized in Weisman and Santa Fe that attendance at major school events like graduation or football games should not be considered "voluntary" even if authorities officially designate it as such. Weekly football games and high school graduation are central parts of student life and students should be able to attend these events without fear of religious coercion."

"Moreover, in both Santa Fe v. Doe and Lee v. Weisman, the Supreme Court expressed particular concern that students could be coerced, through pressure from their peers and others, into praying during school events such as football games and graduation ceremonies. This danger exists regardless of whether it is a member of the clergy or a student who offers the prayer. "

These are supreme court rulings.
