There's the problem with extremes. The Founders intended for public schools. They knew an educated citizenry is necessary for the success of the republic.
The liberals now want public schools to be a monopoly, although it's impossible that the Founders intended that. I thought it was all decided in Pierce v. Society of Sisters, which said the state cannot compel attendance in a public school instead of private. But you know the extremists, the Constitution's only a bump, so they made it financially difficult for the average family to send their kids to private school, and opposed vouchers not because of separation of church and state, but because it would loosen their stranglehold on education.
On the extreme conservative side, others want to get rid of them, although that was also not the Founders' intent. Interestingly, the above court case was in response to state laws intended to use the power of the state to instill "traditional American values" in the kids using the public school system. Basically, conservative Protestants didn't like the influence of Catholic schools, especially in light of all the Catholic immigrants of the time. They tried to cut out private schools to make sure there would be no competition for the minds of a generation, calling the kids "the State's children."
Kind of like the liberals are doing now. Same intent, same disregard for the Constitution, different side of the political coin.
So now you want the power of the state to instill a different set of values in the kids using the government school system? That is what is being done. Have you ever read the NEA literature?
You think the public school can be nonpolitical and not be in the business of forcing someone's particular views of morality? Which morality do you suggest since you support the big government public school which is controlled by leftists with an agenda which is the opposite of that of a large MAJORITY of the parents.
What are you afraid of?
