Also, Tom Jipping wrote an effective booklet to this sam,e point: "The First Amendment: Does the Free Speech Clause Conflict with the Establishment Clause?" [Approximate title.] [His answer was "no," based upon historical adn legal scholarship. In fact, for years in the early 19th Century 12 of the 13 Colonies had official Staate religions: the Library of Congress did an xtensive exhibit on this a few eyars ago called "religion and the Foounding of the American Republic"; Maryland was Catholic; NJ was Presbyterian, other states were Congregationalist, Presbyterian, Episcopalian, Baptist, Methodist, and several other denominations. Thi\us the First Aemndment was intended to prohibit ONLY the establishemtn of a National Religion or National Church.]
Hamburger's book shows that today's radical reinterpretation of the Extablishment Clause, which effectively limitis much religious speech in public forums, was formualted int the mid-19th Century in a period of paradoid anti-Catholic sentiment.
Jefferson was the soel "eccentiric" Founder who wanted to limit the speech of Federalist preachers who were preaching against him, Jefferson.
The 1805(?) letter to the Danbury Baptists, written by Jefferson, only became part of the "constitution" in the mid_late !(th century due to rising antti_cathoilic political views broought into the courtroom>
Of course it doesn't. You can't have a mandatory national religion, and you cannot prevent the free exercise of any religion.--The latter in fact implies the former, as imposing a national religion would prevent the free exercise of any other religion.
So all Americans are free to exercise their religion--as long as it doesn't conflict with the law, of course. "Comrade" Newdow seems to have a religion whose "free exercise" would require Christians to shut up. And that just isn't legal. The First Amendment at work.
