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.
