1)"Your fellow citizens" assumes you are a U.S. Citizen. It was not meant to offend, but simply point out that if you want a thing made into law i.e. gay marriage, then getting a majority of voters to agree with you is the way to do it.
2) No, it does not. Your view is anachronistic. The context the Framers worked under was the Treaty of Westphalia (which was little more than a 100 years prior) and state imposed faiths in general. State religion was the issue, not barring religion from the public square. Since you are interested in Constitutional history go do a study into the state religions (by which I mean the states of the U.S.) of the time period. I think it will help.
3) Your statement was that religious doctrine is forbidden from being made into U.S. law. It reads as a categorical. Prohibition on murder is a religious doctrine. Did you mean to say U.S. Law forbids religious doctrine being made into U.S. law unless the docrine is also found in a non religious context aswell?
4) That is fine.
1. Thank you for clarifying. That said...
Civil Rights should never be opened to the democratic process. Did inter-racial marriages become legal through referendum? De-segregation of schools, the work place, restaurants, etc.? The majority will always find ways to keep the minority downtrodden, as witnessed in Prop 8. This is why the Judicial Branch becomes invovled.
2. a. Our Founding had nothing to do with the
Treaty of Westphalia, something that occurred more than a century prior to the colonies separating themselves from the British Empire. No where in that treaty, which can be found here (you're not the first to make the attempt), do we find any American or Founding principles whatsoever.
b. I've been an informal student of the Constitution since well before the Internets was developed, researching in musty old city libraries. I would suggest you do some independent study of the concern, as you mirror perfectly the false revised history spouted by the Dominionists.
You are even forced to introduce a strawman in an attempt to substantiate your opinion as well. No where have I stated, ever, that "religion was to be barred from the public square". However, religion is indeed barred from US Laws. Bouvier's Law Dictionary is the first American legal definitional source to be created. Entry number four for "ESTABLISH" reads thusly...
4. To found, recognize, confirm or admit; as, congress shall make no law respecting an establishment of religion.
RELIGION... Real piety in practice, consisting in the performance of all known duties to God and our fellow men... 4. But religion can be useful to man only when it is pure. The constitution of the United States has, therefore, wisely provided that it should never be united with the state.
Bouvier Law Dictionary
And concerning your state establishment of religion, the Bill of Rights was ratified nearly a decade after the US was created with the US Constitution. Connecticut merely replaced all references to the Crown and did not have a Constitutional Convention until 1833, when that establishment disappeared, and Massachusetts merely allowed local governments to create taxes to support Protestant teachers, which also was removed as well, in 1813 if memory serves. The Bill of Rights made no attempt, and could not make any attempt, to erase laws already in place.
3. Murder is not an exclusively religious moral, The prohibition against murder can be found in cultures across the globe and across time as well, from the pre-Judeo-Christian Mediterranean and Europe to primitive tribes in South America. This is simply a very poor example to use. Instead, feel free to point out where the remainder of the Ten Commandments can be found in the US Constitution, or US laws in general.
