Thanksgiving was originally established by a religious sect pushing it on the national government. I don't remember the particular sect, but the "holiday" is only a hundred and some years old. The idea of a "harvest festival" is much older, a couple of thousand years at least, celebrated by most cultures to give thanks to their Diety for a full and bountiful harvest with a good supply of food for the winter. I am Christian, my diety is God. I observe the holiday as a religious holiday to thank my God for having sufficient food for the coming winter. In our modern society, it has become a secular holiday, an opening of the "holiday season", nothing more. I merely reject the secular concept of the holiday and observe it as to where it came from and what it means. Most cultures have a similar observation at a similar time to observe Thanksgiving by whatever name at whatever time. In the States, it has devolved from a true harvest festival to "Turkey Day". So to end the "sermon", I wish you all a happy Turkey Day, past.
