Like I said in the other post...why do the Kennedy's get to keep crosses at the graves after Catholic ceremonies on federal land (Arlington); but this other memorial must be removed?
I'll help you out one more time. If you're buried at Arlington or any other federal cemetery, you get to pick the symbol you want on your tombstone. I think there are nine symbols recognized now. The cross, star of David, and crescent I'm sure of and in the last year the Wiccans. I don't know the others. You pick the ceremony too.
The other memorial I believe you're thinking of is theoretically dedicated to all fallen military. All are not Christians and some would resent a cross as a memorial.
How can the pres participate in prayer in Nat'l broadcasts, when kids in school can't on public school ground to the masses? How come easter services can't be held any more at the S. Cal memorial on Fed land; but nobama, the US Pres from Kenya, gets to pray to the world on TV with his wife?
Kids can pray in public schools, silently, aloud, singly or in groups, in the building or on the grounds as long as it does not interfere with other students or school activities and no school employee is involved and there is no coercion of other students. They can't bring in a preacher (or other religious leader) to lead them either.
I'm sure I left out other details, but that pretty much covers it. If you understand that much you won't embarrass yourself.
Vaya con dios.
