I feel the same way about this as i do the flag-burning issue. The real issue here, i believe, is that people make the error of attaching God to a symbol, rather than to their own inner consciousness. It makes no difference what they do to that monument or symbol. Proponents of keeping it in that building are saying, essentially, that removal of the monument will somehow damage God.
This is essentially a fallacious argument, since the very nature of God is that He/She/It, as an all-powerful, all-knowing, all-loving, infinite, incomprehensible and perfect Entity can ever be damaged by something a human does. I find it ridiculous that there are those misguided enough to think they are somehow protecting God. God does not need our protection.
The real issue here is that we are a nation founded on Freedom. Freedom of religion also is included in that, and so the more logical action would to be either put up monuments/ symbols that represent all religions and belief systems, or take them all away.
