“The post-Civil War Klan did not run around in sheets or burn crosses.”
They did, though, wear cloth covers over their heads, with cut-outs for the eyes. Hence the association of the Klan with hoods.
A question for scholars of Catholic Church history:
During the Spanish Inquisition didn't the "Inquisitors" wear white (or red) robes and tall, conical head gear with eye-hole cutouts?
Just curious...
