what do jewish people do on christmas?

wonder what it's like to be living in a separate culture side-by-side with such an omnipresent and potentially oppressive culture as chritianity in the usa. seems there would be no way to avoid knowing about the beliefs of the dominant culture, while the dominant culture has no incentive to learn anything about the minority. judaism, buddism, islam, jehovah's witness, and so on & so forth. there are so many who do not celebrate christmas. what are they doing today?
