I would like to point out that, technically, we weren't considered "Americans" when we shared what is considered the first Thanksgiving with the Native Americans. We were British. Sooo...technically Thanksgiving is a British holiday celebrated in America.
I would like to point out that, technically, it didn't exist until Lincoln declared it as a national holiday just after the civil war as much a symbol of northern victory over the south firmly placing America's origin mythology with the north, so it was never British. As well the Pilgrims were considered heretics and traitors to the crown and escaped from His Majesty's warm embrace under pain of death. The pilgrims were as British as the Pope, so claim either as British at your own risk.
Britains should be thankful Americans don't know or care what Britains are really like or think, very thankful indeed.
PS does anyone know what you have to do a tube of Jimmy Dean sausage to it bring to the quality of British sausage to make sausage rolls,,,
