"All childrens should be praying to God"
Ok, which god? Who gets to choose? Whose god is the "one true god"? Ask a dozen people, get a dozen answers...
"studying the Bible in schools. "
They can still do that, all they want during study halls, lunch, etc. it just won't be forced on students by the school.
"To take this out is to take away morality"
What morality, like in your old testament? Kill, kill, and more kill? (sounds a bit like "Alice's Restaurant"). Kill those that work on the sabbath? Kill kids that are disobedient? Kill entire towns if anyone within is worshipping other gods? Kill your wife on her father's doorstep if she's not a virgin on your wedding night? Beat slaves as much as you want as long as they don't die in a day or two? What about human sacrifice? "Morality" like that?
"The ban on school prayer"
Prayers are not "banned". Kids can pray all they want. Prayer to a specific entity just isn't sanctioned and forced on the students by the school. Maybe just for you we should bring them back, and just for you we'll force everyone to pray to Allah. You ok with that?
"has caused millions of school shootings."
As others have said "MILLIONS?" Citation seriously fucking needed.
