What a dumb judge, how does a Christmas tree offend anybody unless the decorations on it were somehow offensive.
I'm not of any sort of abrahamic religion, neither is my immediate family, or 99% of my extended family, but we sometimes put up a christmas tree (depends if we're lazy or not
). Of course we don't see it as a religious thing, more of it's the custom of the people in this country, so when in Canada do as the Canadians do.
P.S.: I really dislike Political Correctness
