What about my parental right to have compulsory schooling actually teach about the real world as it exists and help me prepare my child for life in that world?

You have no such right as a parent. As a child, you do in fact have an actual Charter right to an education, and your parents cannot interfere with that right.

Even better! That means, I think, that it is the duty of the government and the schools they run to provide the best education possible, not just the education they or activist groups desire.
