Something I had never considered before- seeing as the Cordoba House (variously known as the "Ground Zero Mosque" or Park51) is being built on Park Place, this could very well interfere with a cultural icon dear to the hearts of many Americans.
Anyone who has ever played the game Monopoly knows that Park Place is one of the most expensive properties, and hence arguably one of the most important. If the Cordoba House is built on Park Place, it might very well be seen as an attempt to take over the beloved game of Monopoly.
Those evil Muslims.
