I've never seen it either. I'm from Massachusetts and have 2 kids that are in some fine public schools.
I am closely involved with my children's education in the schools in our town and I must say that this article and many other instances of what goes down in public schools across the country are BS to me. The weird stuff that I read about on FR doesn't go down here.
This is why I will, from time to time, take some Freepers to task for painting public schools with the same broad brush. Not all of them are government indoctrination centers. I wouldn't put up with that kind of BS in my town's schools and neither would any of the Conservative parents I know who also send their kids to the same schools here.
