Tal asks (regarding Ten Commandments Monuments)
"So what law did congress make respecting the establishment of a religion?"
Tal, I am sure you are aware that the establishment clause has long been held by the SCOTUS to apply to state and local governments as well as Congress itself. Or are you saying that the Ten Commandments are not religious? Otherwise, you are interpreting the clause rather narrowly, imo. The SCOTUS is of course itself conflicted on this. In the recent rulings they seem to be saying, "If the monument has been there for a long time and it seems to have more of a historical and cultural context it is ok but if you are erecting a monument today for the purpose of getting the Ten Commandments into the public space we are going to make you take it down." Actually I think that is a reasonable position to take.
