Anyone who opposes public schools because the concept is immoral, is an unenlightened lunatic?
You call things immoral but can have no accurate concept of morality since you don't believe in God. Without belief in God all things are possible since none can be condemned as wrong (evil).
What could you swear to if called to testify in court not "so help me God." How could one protect rights without swearing on a higher power? Man as the measure of all things is folly as shown by the French Revolution, the Russian Revolution and the Nazi revolution. Man acting to create justice based on God's laws and calling on God's help produces great things as shown by the American Revolution.
