It was indeed noble of President Lincoln, in 1863, to declare the last Thursday in November a national holiday. Wait. What? In recent years, controversy has swirled around what really happened at Plymouth Rock. The list of Pilgrims' misdeeds feature everything from Christian fanaticism to child abuse and the cruel treatment of Native Americans. Much later, Thomas Jefferson, who owned 600 slaves, fathered at least six children with one slave, Sally Hemings. Like the rest of us, Pilgrims and presidents are broken vessels, helping themselves to forbidden fruit. Which brings me to an easy peasy Thanksgiving quiz as a public service.
