The mosque being built at ground zero?

[Tank]

To be honest, if they put up their mosque directly across the street, so long as they own the land, and followed the pertinent laws and zoning regulations, they've every right to do so.

Agreed. But having a 'right' to do something may not mean it's the 'right' thing to do. In this case I would have thought that the value of the land they are building on would be pretty high. They could sell the land and build more mosque square feet in places where Muslims would actually use it? I can't think that there would be a huge demand for a Mosque in down town New York on a Friday? I may be wrong but it does seem a poor use of resources.

While I agree with virtually all of this post, the demand for a mosque in Manhattan may well be present.  After all, how many hundreds of thousands of people work in Manhattan?  And how many are Muslim?

Your efficiency argument is to-the-point, however.

As you say there may be a suitable population to warrant a mosque.
