the idea of a white people's organization in any predominantly white society is ridiculous. the reason that minorities feel the need to organize is because they are in the minority-- some people actually have to make an effort to seek out & interact with people who have similar backgrounds, culture, interests, etc just because they are so few and far between. the majority ethnicity & culture does not need to be organized or promoted, because it is the majority-- a member of the majority could put on a blindfold, throw a rock out the window, and prolly hit someone that they have a lot in common with.
"white people oughta have a club too" amounts to little more than mockery and gloating by people who have the luxury of being part of a culture that's essentially controlled by people exactly like themselves. you can switch on C-SPAN, PBS, Joe Millionaire or just about any other american media, and see wall-to-wall whiteness... do we really need a club for it?
edit: just in case the answer isn't obvious-- the majority does not need a club. society is their club.
