I think we can argue the specifics of any individual program. But, the one you cited was California. The 'Iraq' of the modern push to liberalism. Nothing surprises me out of California.
But, liberals have to decide. Ban anything that isn't 'scientific' or is too 'moral'. Or relent on the religion issue. That includes high school too.
I wonder how much better educated people would be if teachers were allowed to teach, and not do all this other stuff parents should be doing. (like informing parents their kids ar too fat, or whatever else)
