Oy. Two activists dressed up as KKK members at an American Kennel Club show to protest pure-breeding.

While the point about show dogs is that they're being abused in order to create a favored, but congenitally unhealthy and in some cases freakish "master race," the parallel abuse alluded to by the mock Klan robes is that ... of the KKK by its victims. Thus the implicit, boneheaded comparison that PETA makes here is that of KKK victims, primarily black people, to dogs.
