Did you know there is a "Holiday Tree" at Rockefeller center? Yes it is now being called by many a Holiday Tree as people in all religions commemorate their holidays at this time of the year with a decorated tree... only they don't. Hanukah symbols are: a menorah, a dreidel, jelly doughnuts (both the food and sexual act), gifts, gelt (coins)... no tree... no tree in Kwanzaa either unless its been changed since I studied it
Use "holiday" to describe the season if you want as there are more than one holidays during this time of the year... that is fine, but it is NOT a holiday tree, it is a Christmas tree... and for the record, they are pretty and fine, so just call them what they are and stop trying to make our holiday which ranks as 8th on the "Most Important Holiday" list in the Jewish Calender and make it synonymous with yours... it isn't that important nor is it in anyway like Christmas.
