I have no problem with a school teaching about God...hell, they can open a BIBLE class as far as I'm concerned.
Pray all you want - As long as they give students the right to OPT OUT, as well, and/or give other students of different religion the opportunity to pray to their deities.
It shouldn't be about less, it should be about MORE.
Open the schools an hour earlier for prayer services and watch everyone's tone change.
Things like this are not a problem when it's an OPTION. It's a problem when it's REQUIRED.
When it's MANDATORY that you follow God and the Bible to get a fair trial in America, the same trial for someone who doesn't practice the laws of the Bible as someone who does practice them, then something is wrong.
