The message Michael Farris had come to deliver was a simple one: The time to act was now.

For decades, Farris — a conservative Christian lawyer who is the most influential leader of the modern home-schooling movement — had toiled at the margins of American politics. His arguments about the harms of public education and the divinely endowed rights of parents had left many unconvinced.

Now, speaking on a confidential conference call to a secretive group of Christian millionaires seeking, in the words of one member, to "take down the education system as we know it today," Farris made the same points he had made in courtrooms since the 1980s. Public schools were indoctrinating children with a secular worldview that amounted to a godless religion, he said.

The solution: lawsuits alleging that schools' teachings about gender identity and race are unconstitutional, leading to a Supreme Court decision that would mandate the right of parents to claim billions of tax dollars for private education or home schooling.
