The cross was already a landmark. I really do not see any harm in letting it stand until or unless it becomes unsafe or the land is needed for some other public use.
I was very upset when the Taliban blew up the two colossal statues of Buddha in Bamiyan Province. It was a spectacular piece of religious intolerance. This cross issue is not really about of the separation of church and state, in my mind. Rather, it is really one of religious intolerance in the guise of civil liberties.
Like I said before, I would have a problem with a new religious oriented structure on government land but IT WAS ALREADY THERE. It is a landmark. There is a minority of people who do not like it and are forcing their views on the masses. I would like to see the people vote on it. Perhaps the land can be leased or sold to a private group, thereby removing the government from the equation.
