This is an issue that's been bugging me. I actually get twinges when this is brought up. Prayer does not belong in public school. And where did this come from? I didn't have prayer in school while I was growing up. Thankfully I didn't even have one of those coaches asking God for victory. My coaches were more practical, "Get out there and work you asses off" is pretty much what their instructions consisted of. I guess they thought that God would have better things to worry about than my volleyball games or track meets. I guess my coach didn't think about divine intervention winning games for us, he wanted us to learn to do it ourselves.
I guess I get riled on this topic because I know the majority of people that push for prayer in school would have absolute hissy fits if prayer was allowed in school and their little Johnny came home from school with tales of little Suzie praying to the Goddess during prayer time. There is no way that these right-wing fundamentalists would ever condone, a Muslim or a Wiccan, to ever pray near their child.
It's one of those can't have it both ways situations. If they got their school prayer, they better be tolerant. And so far, in my experience, the ones screaming the loudest are the least tolerant.
So, in my opinion, if you would like your child to pray, take them to church.
