Yeah, that Madison, Jefferson, Theodore Roosevelt, and the rest, what a bunch of left-wingers, eh?
The "intrepretation" of the establishment clause which you dislike is the same as theirs, son.
Are you sure you really want to try to categorize this as "left-wing", microgood?
Actually, the First Amendment as written didn't apply to states or localities at all. Such application came about as a consequence of the Doctrine of Incorporation, a federal judicial creation based (purportedly) on the 14th Amendment. Neither Madison nor Jefferson envisioned federal courts interfering with the states or localities on church-state matters.
Likewise, when Tocqueville wrote of separation of church & state, it was in an era in which states were perfectly free to associate with religion.
There are differing opinions on what constitutes the mingling of church & state. Does it mean government must operate on the assumption that God doesn't exist? Or is it the more modest assertion that government shouldn't subsidize a particular denomination, but is free to recognize God's existence?

Just some things to consider!
