Geert was at Ground Zero on 9/11 this year and gave a great speech with some interesting information about where they got the name of the mosque from. You can't refute the significance.
Full speech here, along with video if you don't feel like reading:Most Americans do not want this so-called Cordoba Mosque to be built here. They understand that it is both a provocation and a humiliation. They understand the triumphant narrative of a mosque named after the Great Mosque of Cordoba which was constructed where a Christian cathedral stood before the land was conquered by Islam.
