As a lifelong resident of NYC I have always known that Jews and Roman Catholics here get it . When one religion's free expression is endangered, all religions are in danger.
That is why we never have a problem here with THE Christmas trees in Rockefeller Center, in front of Court Houses in Brooklyn and Manhattan, or Menorahs in the same locations. The are called Christmas trees not "holiday" trees, and Menorahs, not "candelabra".
No problem with display of Ten Commandments, crêches, or other religious symbols that takes place in other places.
The ACLU won't mess with NY. As former Mayor Ed Koch, and current Mayor Mike Bloomberg put it... "we love Christmas"!
It has just about become that silly -- "holiday trees" and "candelabra," indeed. The next thing, the radical secularists will demand that a crucifix be called "that hanging man" and a Torah scroll be called "that piece of paper."
Of course. It's good for business.
