A. Why not? It is the most universal of all American holidays. Jews celebrate Thanksgiving everyday, as we have a multitude of blessings and prayers thanking G-d for all the good in our lives. Our family hasn’t always had Turkey, but it is a good time to gather round and be thankful for all the blessings in our lives. When things went well, the Founding Fathers thanked G-d, not the bull market. One year we were invited by an alumni couple to a full Thanksgiving Feast, and we very much enjoyed. Some years we had alumni up here for the Thanksgiving Shabbos weekend, and sometimes it’s one of the special family-only weekends we do with our kids. Some Jews refrain from celebrating even secular non-Jewish holidays.
