Isnt that the truth

I'd wear it.

god has nothing to do with it in my opinion

God is perfectly welcome in any school I know of. You're just not allowed to force him on anyone.

God was never forced on anyone when I went to school. We took turns reading a passage from the bible, said the pledge, Lords Prayer. If you didn't want to participate that was fine, I don't ever remember anyone being singled out.

We had several Jehovah's Witness in our school, in fact I grew up right beside a family of that faith.
We also had a Jewish family in our school. Never was a problem.

Any kid who wants to pray or read the bible is still perfectly able to, there's just nobody organizing it. And if I recall correctly, the Bible actually says that prayer should be voluntary and private

Could someone explain the theory?

There used to be prayer in public schools. That was ended sometime, I'm not sure when, late 1960s or so?

Then...what? God got angry about that and sent young men with guns to kill school kids, for retribution because adults made that change in policy?

If that's not the theory, what is? What's the cause-and-effect theory?

What do you see as being the chain of causation (to use a fancy term)?
