"My question is why aren't they called "Holiday Trees"?" ===============================================================
BnB...
Perhaps because the "holiday" they celebrate is Christmas???
If the secularists have their way, "holiday trees" is exactly what they will be called. But there is a problem even there -- the word "holiday" comes from "Holy day". Ooooops. Can't have that. They will have to come up with something else. "Seasonal trees"???
