Which is an argument for voting with your feet, vouchers or abolishing public education but not one for centrally located technocrats, bureaucrats or judges deciding local issues.
In principle I agree with you. However, until the libertarian millenium arrives, they're using my tax dollars to educate my kids, and I'm darned if I'm going to have them taught creation myths when they're supposed to be learning science. Bad enough they learn liberal shibboleths when they're supposed to be learning history.
