The Klan was founded in Polaski, Tennessee, in 1866 by six Confederate officers. One of them was Nathan Bedford Forrest, the first Imperial Wizard of the KKK.
You are disputing the historic record. Forrest did not originate the idea. Even if he attended the first meeting, it simply wasn't his idea. He never claimed to have originated it. Another man is always identified as the originator.
This is kind of like getting closer and closer and closer to the Schwarzschild radius. Before you ever arrive at the singularity, time will have slowed to such a crawl that an outside observer would see that you were near, but not "at".
