Please answer a question about the following article about Separation of church and state in the United States:

Some scholars and organizations disagree with the notion of "separation of church and state", or the way the Supreme Court has interpreted the constitutional limitation on religious establishment. Such critics generally argue that the phrase misrepresents the textual requirements of the Constitution, while noting that many aspects of church and state were intermingled at the time the Constitution was ratified. These critics argue that the prevalent degree of separation of church and state could not have been intended by the constitutional framers. Some of the intermingling between church and state include religious references in official contexts, and such other founding documents as the United States Declaration of Independence, which references the idea of a "Creator" and "Nature's God", though these references did not ultimately appear in the Constitution nor do they mention any particular religious view of a "Creator" or "Nature's God."

What do these critics argue couldn't have been intended by the framers of the constitution?
prevalent degree of separation of church and state
