“And I have no doubt that every new example will succeed, as every past one has done, in shewing that religion & Govt will both exist in greater purity, the less they are mixed together.”
~ James Madison, letter to Edward Livingston, July 10, 1822
Since that time the courts have interpreted it differently, according to the times and constant 're-interpretations', but the Constitution speaks for itself. The Courts have drifted away but the Constitution remains the same.Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
Now for the record, and as a Christian, raised Roman Catholic, since lapsed, I don't really have an objection to people displaying what they want, as long as we can all respect each others right to believe what we want....That word "respect" goes further than just me allowing non believers to be assholes to those that believe, and vice versa. It means not doing things specifically to disrespect what others celebrate as holy to them....I doubt truly that Satinists do what they do with any respect at all, so in my eyes they don't deserve such.
Establishment Clause - Wikipedia, the free encyclopedia not the establishment of Christianity itself.
