In the current culture wars, religious liberals tend to ally themselves with the educational establishment against those on the Religious Right who are attacking the public schools. In politics and theology, I line up with the left. Nonetheless, I believe with the right that public education is hostile to religion—not least to liberal religion. The problem isn't the absence of school prayers. Schools respect the religious liberty of students in prohibiting religious exercises. There is no hostility to religion in that. The problem is that systematically excluding religious voices from the curriculum makes public education fundamentally illiberal—something that, ironically, most liberals fail to see.
