Sure, call football teams the "Pipe-of-Peace-Smoking" Sioux, Illini, and whatnot.
"An Indian ... seized Henderson's daughter, 'sweet and pretty child of two, and beat her savagely over the head with a violin case, smashing her head horribly out of shape. Then he took her by her feet and dashed her brains out against the wheel of the wagon, spattering her mother with blood and brains. Another fiend took the nine-months-old boy, hacked off his limbs with a tomahawk, and threw pieces at the mother. Then they made a big fire and tossed featherbed, woman, and mangled children into the flames."
