GZ Mosque Design Has Visitors Walking on Stars of David

The developers of the Ground Zero Mosque have released three architects images of the planned building. The design seems to be using the Star of David, a widely recognized symbol to represent the Jewish people and central element in the Israeli flag, as a design element. Notice how people will be walking on the Star of David. Click on the third image to get a close up.

I think this is a sign of disrespect. Would Muslims be comfortable walking on symbols of their own religion?
