I am Canadian, and when I was small, we went to visit my aunt's family in America for Christmas. My aunt had married into a Jewish family, and my older brother told me that her family did not usually celebrate Christmas, but they would this year just because we were coming. I knew nothing about Judaism, so I assumed, and believed for several years, that Americans (the only differnce I understood being our nationality) did not celebrate Christmas.
