Gurren Laggan is a testament to the state of the world today in a racial sense. The Dai Gurren represent the minorities of the world that are being suppressed by whites (Blacks, Hispanics, Gays, etc.). The beast men represent the white race in its current state. They are superficial and cloned. Lord Genome is their leader and he has spiral energy because he isn't inept like the average white person. All minorities possess this energy because they are striving to over come the clones and thats why they are so easily defeated. People of color possess heart. The anti spiral represents the enslaving white race of old. They also possess spiral energy because they were at one time able to enslave all the minorities. But just as in Gurren Laggan the minorities of the world are now rising up against white oppression and will soon throw it off completely.
