Forced to defend an unusual educational practice, unschoolers take great care as to how they describe it. Buchanan hedges a bit when asked if she's an unschooler. She does put books in front of her children from time to time, which is anathema to orthodox unschoolers.
I can't imagine that any unschooler would actually say the act of putting books in front of their children is so repugnant. Forcing them to read the books or giving them quizzes about what they learn from the books -- that's another story. Perhaps I am reading too literally.
