Saint Nicholas, Santa Claus, Father Christmas, Kriss Kringle (?!)..., is a fascinating partly historical, christian, partly legendary and folkloric, and mostly highly commercialized morph. People all over the world call him different names and celebrate him in different ways. Now the newest fight is about his skin color! Wikipedia entry on Santa Claus summarizes his phenomena pretty well.
My take on it? As long as the effect of the traditions will put a smile on ones face, help to bring people together, and help someone in difficult times I'm all for it! Happy holidays!
