Like liberal programming in public schools? The voucher system to escape it? The best private schools ask for more than what is in those vouchers, also, and this is the truth, the best private schools endorse religion.
So your kids are getting programmed either way. Either they become liberal, or they become a cultist.
I prefer my kids to being programmed liberal, at least I know they have a very good chance to grow out of it!!
I went to a liberal arts college. My best professor said "I've failed if you can tell what my politics are."
When we studied political philosophy, he wanted us to build arguments for (and criticisms against) every major political theory. He wasn't concerned about our personally held beliefs - he just wanted us to be able to defend whatever position we held. There was a healthy mix of liberals and conservatives in this class, and he didn't favor one side over the other, he was concerned at the micro level of how premises logically support a given conclusion.
My most passionate professor was a pithy, avuncular British conservative who had trouble hiding is contempt for liberal positions (-by liberal I don't mean classical economists like Adam Smith and Milton Friedman, but post sixties American New Deal Liberals). Anyway, this conservative professor was far less concerned with the mechanics of argument, and he did not reward carefully argued positions unless he agreed with them at the gut level. You needed to conform to his values/beliefs to do well in his courses, but at least you knew that going in. He believed that there was one true Reality and set of Values, and it was his job to deposit these things in the heads of his students, who were expected to be passive receptacles of truth rather than active builders of knowledge/Self/World. Our job under him was not to question Reality but to accept his version of it. As in Church, he was like a holy priest delivering God's Word. However, he was so unbelievably charismatic and enjoyable to listen to (with his dry wit), that I happily accepted his contempt.
(The first professor above was extremely liberal. He played chess routinely against one of my classmates, a deep conservative, who aced all the liberal professor's classes because he could defend his positions with good arguments. The point is that he didn't punish this kid for being conservative
because he (the professor) was a liberal. And if you study the liberalism of the European Enlightenment (Kant et al), you realize that the most important thing about belief is the ability to eschew the truths of faith/religion/tradition/habit/culture for the truths built through careful argument - reasoned belief. Some conservatives hate this because, as they said during the European Enlightenment, you can't create an argument for a set of values that runs contrary to the ones handed down by God/Nation/Tradition. There is no such thing as personal freedom when it comes to beliefs and values. Students must accept the world they are handed by their superiors. Period.)
