Doonesbury by Garry Trudeau for August 16, 2015
George: I have to teach this? You do, George. You have a family to support. So why did Texas secede? Because of sectionalism, states' rights, and slavery, in that order... Travis: Mr. Safer? George: What is it, Travis? Travis: I know that's what our new textbook says, but listen to this... "The African race... were rightfully held and regarded as an inferior and dependent race, and in that condition only could their existence in this country be rendered beneficial. The servitude of the African race... is mutually beneficial to both bond and free, is abundantly authorized and justified by the experience of mankind and the revealed will of the almighty creator..." George: That's enough! What is that? Travis: The Texas Declaration of Secession. The word "slave" appears 18 times. George: Travis, what did I say about outside sources? Travis: That they're liberal, but this was written by racists!
