I tend to agree with James Madison:
"Every new & successful example therefore of a perfect separation between ecclesiastical & Civil matters is of importance. And I have no doubt that every new example will succeed, as every past one has done, in shewing that Religion & Govt. will both exist in greater purity, the less they are mixed together."
I think we fall into the trap of thinking that kids aren't allowed to learn things outside of class time. Education of children is also the responsibility of their parents, family, and community. I know that people have less time now than they did in the past, or at least it feels that way. However, education and learning should be something we do all of the time, not just in class.
