The 50’s? I have very clear memories of celebrating Thanksgiving in the early 40’s, and the only real change to the tradition has been the evolution of televised football! And, as the professor points out, the precedent for such a feast can be traced back to time out of mind. Labelling the Pilgrim feast of 1621 as “The first Thanksgiving”, or even the “The First American Thanksgiving” may not be strictly accurate, but to call it a plot by the government is revisionist history! That feast in 1621 happened to be significant, colorful, and documented. Not a bad choice for a point of reference in history, but I’m sorry if you have a problem with that.
