Reply #1: The fact is this

School prayer prohibitions (as mandated by two USSC rulings in 1962 and 1963) are in practice very hard to enforce.

If the overwhelming, almost unanimous majority in a town is of a particular faith and they want to recite a prayer with the approval of the school, well, it's probably going to happen. Realistically, it's not like the police are going to show up to order the prayers to stop and arrest people who persist.

I know people who attended public schools in the 1970's, 1980's and 1990's, and they have all told me that prayers took place anyway with their schools blessings. This was long after the Court's rulings in Engel v. Vitale and Abnington Township v. Schempp.
