You've never had a kid go to private school, have you?
You have all the freedom in the world. Of course, your kid has no inherent right to play baseball, so no freedoms are given up if you decide not to do business with them!

You have all the freedom in the world... especially to take your kid out of the program if you find it "socialist"
