This has nothing to do with silver. If you dont like the monument and what America stands for then go live in Iran where they have no freedom and they dont believe in "idols" All the Christians seem to do is put down other religions and insult people-that is not why Jesus came to earth!
Matthew 10:34 Do not think I came to put peace upon the earth; I came to put, not peace, but a sword. For I came to cause division, with a man against his father, and a daughter against her mother, and a young wife against her mother-in- law. (Not everyone will agree with the teachings of Jesus , therefore there will be division)
