All moral and ethical positions are matters of opinion and wide open. Why do you limit yourself to those based on religion?

The Constitution is now where near so specific about religion that it forbids passing laws that I support as a result of my religious beliefs, Amos. It prohibits establishing a religion and nothing more. The Founding Fathers, even those traditionally considered anti-religious would be astounded at the suggestion that the dictates of someone's conscience had to be excluded from public debate. It denies me my 1st Amendment right to free expression. Argue against what you will in the public forum, but don't try to exclude anything from it.

Even if you could convince a judge to construe the Constitution they way you say (since the public would never agree to it any other way), where do you draw the line? "Thou shalt not steal" is one of the Ten Commandments. Should we throw out a law against theft because it has a religious origin? Who will decided what is religiously based and what is not? You talk about forcing society to adopt "creeds and moral dogma" of some sect. All you want to do is replace them with some politically correct creeds and moral dogma that's consistent with your secular religion.
