Well it's pretty hard to have celebrations without symbols. Maybe we should be happy about this story then?
I am just saying a Christmas Tree does not represent the faith of Christianity, HOWEVER a Menorah does represent a religious symbol in Judiasm. I am sure if they put up a Menorah that would open up more people possibly wanting to put up a Nativity Scene another religious display.
Do Christmas lights hanging up in Department Stores or on City lights represent anything religious? The Rabbi was wrong if he thought the Christmas tree represented the birth of Jesus.
