The Blue Man Group should sue.
Caucasians do not have a strong ethnic bondage similar to blacks or Hispanics.
On the other hand, Caucasians have always been members of exclusive ethnic clubs with natural bondage.
For instance, my wife is a member of the Danish-American Society and the Danish-American Chamber of Commerce. I have accompanied her to Danish-American conventions, and all I saw for the whole weekend was lily-white, tall, good looking people :-) [Yeah, I like long-legged, blonde Danish women]
I'm sure that an Italian-American club, or an Armenian-American club or a Greek-American club will have a much stronger raison d'etre than a Caucasian-American club.
