Interesting, but lets dissect a bit. The Ku Klux Klan was based on the fact you could only be white and christian, lets take a look at a snippet from the wikipedia page (all verifiable by going there yourself, I won't post the URL lest I get accused of being an enabler/supporter...I am not!!):

Its appeal was directed exclusively at white Protestants; it opposed Jews, blacks, Catholics, and newly arriving Southern European groups such as Italians.[24] Some local groups threatened violence against rum runners and notorious sinners; the violent episodes generally took place in the South.[25]

The black panthers you just answered, one had to be black and follow communist/socialist views.

Ask a palestinian arab or secular israeli jew if you think there is no orthodox/extremist jewish racism/terrorism. These links I will post:

You call what I post racism. I maintain it is an ideology that each faith/race twists to their own ends, based on their interpretation of an ancient holy text, or political view, or ethnicity. But that DOES not make me racist! Do you get it NOW, do you!! That said I still support israel 100 percent as a beacon of democracy and a hub of science and technology in what is otherwise a war torn wasteland, they truly made the desert bloom, and that is beyond doubt. My last post on here, no reasoning with israel hating liberals like you and CL.

Good luck ace!!!
