That problem is that parents who want to expose their children to more knowledge and better education have no voice -- of any kind. A small group of parents objecting to something violating their niche belief will absolutely nullify the voices of any number of parents thinking otherwise.

There needs to be greater ability on the part of educational organizations to be able to parse the unencumbered learners from these minority case.
