Believe me, my friend. Someone would try to make that case and worse and it would cost local school boards hundreds of thousands of dollars in legal fees.
I agree with you totally about public financed propaganda and I don't want my children harassed by private financed propaganda on public property either. Your cited wrongs don't make another wrong, right.
There are many parents who don’t want their kids harassed by the Secular Humanist, atheistic, agnostic, pro-socialistic, anti-Judeo Christian propaganda found every minute of every day in their kid’s government indoctrination camp!
Yet, if these parents refuse to cooperate, armed police will soon be at the door. Remember! Behind every government school teacher and government employee is a policeman with a gun on the hip! ( Real bullets in that gun!)
Government schools are an offense against freedom of conscience and are a First Amendment nightmare!
What you fail to understand is that the equivalent of "Mao's Little Red Book" and "NAMBLA" are ALREADY in your children's school materials courtesy of the National Education Association, whose leadership is a wholly owned subsidiary of the leftist agenda. They're getting it TODAY, as you sit in ignorant bliss. Explain to me now "NAMBLA" is significantly different from "gay, lesbian, bisexual and transgendered"--which is ALREADY BEING TAUGHT, and WITH your tax dollars.
My "wrong" is the only approach that will "right" the situation. It's called "freedom of speech", a concept once understood by all Americans, and today understood by virtually none.
