All should remember that the Klan existed in three different eras-as three very different organizations. Any meaningful comparison with mainstream or near mainstram political
organizations can only be made with the second Klan Which was a social, political,and electoral movement and not primarily a terrorist organization like the first and third versions of the Klan.

btw, in the scale of the universe even golfballs and grapefruits are similar because they’re both round, have a similar surface pattern and are within the same order of magnitude

@ David A.: Also spot on.

Obviously these marches were conducted with wide support and were very public and out in the open. It is fitting that the White House is featured prominently in some of those photos. President Wilson (the first “progressive” president?) was himself a member of the klan. And the Nazi party did have a fairly large and open following here in the States right before the second world war. As did the communist party in the early ’30′s. These movements where very public and open, which leads me to believe that “vast conspiracies” of any ideology are not what you have to look out for. It’s the movements that are right smack in front of you that you have to watch out for.
