Apparently you need a history lesson.
From: http://en.wikipedia.org/wiki/Nathan_Bedford_Forrest
"Forrest is also one of the war's most controversial figures. Although he was accused of war crimes at the Battle of Fort Pillow for having led Confederate soldiers in an alleged massacre of unarmed black Union troops, the accusation was later completely rejected by a 1871 United States Congressional investigation."
"After the war he was alleged to have participated in the founding of the Ku Klux Klan. Despite rumors that he was the first Grand Wizard of the Klan, the Congressional investigation of the Klan in 1871, which included several former Confederate generals, undertaken by Radical Republicans concluded that Forrest did not found the Klan, was not its leader, did not participate in its activities and worked to have it disbanded.
wikipedia isn’t the most reliable. Anyone can add or delete material there.
Most sites list him as one of the original organizers of the KKK and its grand wizard.
So, what about Nathan Bedford Forrest? One historian labeled him, “the clear, unfettered genius of the Civil War.” Others see him as a racist monster, responsible for the massacre of blacks at Fort Pillow on April 30, 1864. Never asking his soldiers to go where he wouldn’t himself, he had 29 horses shot out from under him. He entered the Confederate forces a private and left it a general. On the other hand, he helped start the organization known as the KKK and served as its head from 1867-1869.
