I want to know the answer to the following question:
What does Hamburger feel the modern concept of separation of church and state is rooted in?
All the background I'm provided with is that "Critics of the modern concept of the "separation of church and state" argue that it is untethered to anything in the text of the constitution and is contrary to the conception of the phrase as the Founding Fathers understood it.". Is that enough to answer the question?
Answer: no
