Most cities have come to their senses and realized that there really isn't anyone out there who finds the word Christmas offensive. And if they do then they don't matter since they aren't Christians and they are going to hell anyways.
Kidding. The reason that they don't matter is that with so many other things that people could pay attention to or get offended by Christmas would have to be at the very bottom of any semi-intelligent persons list. If it's on the list at all.
