Well, does the KKK intend to terrorize people or not?
Yes and no. I'm sure its members would love to however the organization that is the Klan today simply lacks the ability or will to carry out any sort of terrorist act even intimidation. The Klan was pretty well destroyed by the criminal and civil suits launched against them in the 80s and 90s. Thus as a unified entity one can not say they are today a terrorist organization. Some of their members may indeed be terrorists but on the whole most of the organization is fragmented.
