I always found it interesting that the left was so uniformly adamantly opposed to displays of the 10 commandments on state capitol or courthouse grounds. Especially as the most corrupt politicians tended overwhelmingly to be Democrats. My take was that this sprung from Religion in general being the source of our morals and ethics, the left would of course see any moral or ethical guidelines springing from religion as creating a hostile work environment.
Here's a better explanation complete with optics:
Since their political philosophy is pretty much devoid of moral or ethical absolutes, to the left, the presence of the commandments on the building lawn is like showing a cross to a vampire.
Note also the love shown by the left toward Islam, the only major religion to include broad exceptions to every moral and ethical commandment.
