Adam Smith, Von Mises, anything & everything written by our Founding Fathers, but make sure you get beyond the big names. If you can find sermons of Revolution minded preachers, it will help you rid yourself of the separation of church nonsense that’s been fed to you. Also, “Common Sense” by Paine well worth your time.
Don’t stay away from the alternate voice, read Alinsky so you know your opponent’s playbook. Read Marx, Rousseau, Voltaire & Mao’s little red book.

Separation of church and state is not complete nonsense. There is a middle ground. The founders were on both sides of this controversy.
