And it makes a captive audience of students who don't want to hear a prayer. This myth is really a way of attacking free speech itself. If nobody can speak unless everyone agrees, then we have censorship, not freedom. It's dangerous to impose silence simply because someone else disagrees. The best model to follow is how we conduct the Pledge of Allegiance.
Most students recite it, but some sit silently, and a few even leave the room.
The Supreme Court ruled that no student can be compelled to say the Pledge, but those who object were not permitted to silence those who wish to say it. This is a perfect model for voluntary school prayer. This is a scare tactic, because there's no real threat of this type. It never surfaced when school prayer was common, and any such efforts would remain exceedingly rare. Just as free speech does not give a student the right to interrupt and change topics in class, however, the RFA does not permit disruptions.
