Historical value
We also preserve the ceremonial rock paintings of the native americans... doesnt mean that they are preserved for their religious value.
The fact is the constitution forbids the government supporting religious icons like the one in question. The people calling for our government to follow the constitution are not hateful lunatics for doing so.
Do you believe that the government should follow the constitution, Yes or no?
If yes then what is your problem with people demanding it?
If no, then what is the point of a constitution?
