Unfortunately, they are correct, marshmallow. Using the Bible to swear an oath of office in a secular nation is hypocritical. If Italy declares itself a religious nation, then it may follow the precepts of that religion. It was formerly understood to be Catholic (although not formerly), although the percentage, like the numbers across Europe, are falling. To restore the crucifixes to all classrooms is relatively simple. Declare Italy a Catholic nation and all state institutions to be Catholic; they could model it on certain Oriental or Muslim state constitutions. Now that could be Catholic or Latin Catholic or Roman Catholic. The principles would be the same.
I say simple, and it would be simple. Easy, on the other hand...
Calling it like it is, Mark. Spot on.
