I won't quibble. Moore posting the monument amounts to a self-expression of a government body. The government body known as Congress expresses its wish to be given strength by G*d before opening proceedings. You haven't addressed my distinction between self-expression and substantive treatment as regards giving preference.
He has given anyone who will ever set foot in his courtroom who is not a Christian, reason to try and get the case dimissed. I know that if I were a Muslim standing trial, I would challenge Moore's ability to remain impartial.
Hogwash. Religious freedom and impartiality are guaranteed by the Constitution. I'm sure you wouldn't say that government bodies must accomodate every foolish fear in the head of a Muslim standing trial (for example) no matter what the fear.
So it is incumbent upon you to explain why seeing the monument and understanding the idea behind it may inculcate a reasonable fear.
And here's the Chief Magistrate of Alabama openlty stating that he's NOT impartial.
That the only way one can expect Justice in his Alabama Court is to invoke the God of Judeo-Christian beliefs.
"To suffer the civil magistrate to intrude his powers into the field of opinion and to restrain the profession or propagation of principles on supposition of their ill tendency is a dangerous fallacy, which at once destroys all religious liberty, because he being of course judge of that tendency will make his opinions the rule of judgment, and approve or condemn the sentiments of others only as they shall square with or differ from his own." -- Thomas Jefferson
