My understanding is that it is not a mosque that is being proposed, first of all. My understanding that the proposed project is to be an islamic cultural center -- I suppose that refers to some kind of educational facility. This basic misunderstanding is the first thing that has added to the poison of the alleged debate about the matter.
But even if it was a mosque I would support its construction at the proposed location. There is one thing people should think about. I 'm not going to rehash any arguments already made about freedom of religion, the constitutionality of the matter, security, and so forth.
Because the attacks on the World Trade Center and Pentagon were carried out by people purported to be Muslims (there is a serious question as to their devotion -- what with some of them regularly going out drinking and whoring), this is PRECISELY why the center should be built near Ground Zero. One would think we as Americans would want to show that we don't jump because this or that Boogey Man is invoked.
