"Please - need I list all the past decisions that DID RESTRICT people's right to pray in schools"
The above comments are both yours.
This statement was actually referring to decisions that restricted prayer in any sense - which is a violation of the Free Exercise Clause. I do not believe The Constitution allows for the courts to restrict any form of religious expression by individuals, whether they be teachers, football coaches, or student valedictorians. You can disagree but you can't parse the Establishment clause or show me from the founder's writings where schools are considered off limits for any prayer situation. In fact, the founders encouraged the reading and teaching from the bible in schools.
