I don't have a problem with the display of the ten commandments in this manner, as they are most certainly an example of ancient law. They are certainly not the basis of all law, as ancient societies without the ten commandments most certainly had prohibitions against, stealing, murder, etc. I would note the absence of Jesus from the same building, for those who missed it.
A law that prohibits the establishment of a religion most certainly guarantees freedom from from religion with regards to the the government imposition of same. The only argument is where the line is drawn. The founding fathers knew well of the tyranny of the majority.
That is correct. Key part being the government imposing it upon the citizens (and IMHO a display is not "forcing" or "imposing" anything). Too many people (atheists mostly, but also people of other faiths besides Christianity) take it to mean that religion should be totally absent from society. "Keep it under your hat" I believe was the term used up thread. The first amendment does not do this. If the government required that all public buildings display the 10 commandments, or that citizens must visit a display of the 10 commandments on a daily basis under penalty of law, then that would be an imposition. And save the argument that since tax dollars were used to build those buildings. The taxes were agreed to (by our representatives) like it or not, and until the USSC says that taxation is unconstitutional, then that's what we've got.
