Actually really disturbing.
Isn't this the norm in many countries? Doesn't the Labor Party of Norway run a summer camp? Don't most political organizations have youth wings? What is wrong with this? If someone wants to raise their kid in a Libertarian household, they have a right to a Libertarian education. My cousin, who is literally a genius, goes to an exclusive school run by the Koch brothers. I go to a Christian school (it is a Dutch Reformed school), and the Black Panthers ran all kinds of programs for the youth in inner cities which were very beneficial to the community.
I don't think political summer camp or young whatevers exactly equates with it being the entire curriculum. Anyways, I agree with Marokai.
