"People have a right not to have their children, on their own tax levy, indoctrinated with secular humanist and atheistic-materialist values"

Absolutely, but schools are SHARED resources.  My atheist, secular, humanist taxes are lumped in right beside your religious taxes.  How do we reasonably separate them so your money goes to your concerns and my money goes to my concerns?  Or ... do we have common concerns we can pool on, and only *some* selective concerns that truly require us to spend differentially.

Both our kids need to know math.  Can we put them both in a math class, and when that class is done, you can take them to church and I can take mine to the ROM?  There's no reason why a shared public system cannot work for every faith ... and those of no faith.
