The community center at ground zero could have been a great idea, if it also included other faiths:
After September 11, 2001 my then wife (now deceased) suggested the following to an engineering firm: Build a large building at ground zero honoring the 3 main religions of the town: Christianity, Judaism and Islam. Her design looked like the tablets of the ten commandments and had the symbols of the great religions on it (she also included the Yin and Yang symbols). She did not say what should be in the buildings.
Maybe there is something there: Honor the dead, but honor all of their religions.
Quickly approve a YMCA, a Jewish center and the Islamic center on the same site. This will be a great win for moderates, and an actual defeat for extremists of all religions.
Being an occasional agnostic/atheist myself I would like there to be an actual cultural center as well.
That way my religion, Pink Floyd, will also have a chance to win followers.
Or maybe There should just be a good, larger than Rockefeller center, ice skating rink...
