First, quash the rights of the free exercise of religion and then their natural defender perishes and we get “educated” souls in Law, Press and College who barely understand the basics of civil conduct let alone Free Speech. Once we allow the free exercise of religion, then the rights of free speech are very well defended.
The “Separation of Church and State” has two huge problems. The first is easy, the word Church is neither found in the US Constitution, any of its amendments, the Federalist Papers nor the Declaration of Independence; thus, anyone who told you that it was in the Constitution lied to you. The second is more systemic.
Believe it or not, your First Amendment Rights are a fulfilled campaign promise by James Madison to the Baptists and Lutherans of the state of Virginia — http://www.barnesandnoble.com/w/founding-rivals-chris-derose/1100208408 It seems at the time there actually was an established religion in Virginia the Anglican Church which took to using the power of the state of Virginia to abuse others. To simply have a Sunday morning Church service, Meeting at a Mosque, Meditation at a Temple, Atheist book club meeting, open discussion at Starbucks or Attending a Synagogue on Saturday one actually exercises every single First Amendment right. If confused about what the First Amendment actually means — one might want to ask a well educated Baptist or Lutheran minister. You will be surprised what the ACLU might not have told you.
Enabling the free exercises of religion: Anti-Establishment, the Government evades establishing the legal right for one religion to use the power of government to abuse all other religions. If confused, see the United Kingdom — a constitutional democracy with an Established Religion. The Netherlands has a Established Church. India has established Hinduism. Saudia Arabia has established Islam. There are other examples of Established religions with real powers granted to them by the government. To print holy books, meeting notes and persuasion pieces, one needs freedom of speech and of the press. To keep notes concerning confidential charitable or benevolence work, one needs the ability to keep private records the government cannot have a copy of without probable cause or a warrant. To hold meetings one needs the freedom to peaceably assemble. To meet with approved members and even to eject an unwanted member — malcontents, an insane person wrongly supposing they are Arch Angle Michael, or even the press from a sacred assembly — one needs freedom of association. To address government intrusion in to zoning regulations, hindered permits to build, noise ordinances related bells, gongs, flying doves, organ music, public prayer. Pollution ordinances related to incense. Alcohol ordinances related to sacred wine. IRS tax maneuvers related to free speech related to incorporation status. Religious ordinances related to distinctions between men and women in dress, privacy or bathroom facilities. All these required the ability to petition the government for wrongs suffered at the hands of government.
