As of 2015 the object of eugenics have shifted from trying to create a superior race to creating a single race. I think that the mixed race will become the master race after they take over the world with their extreme good looks. The Mixers will have the athleticism of the Blacks, the sophistication of the Whites, and the dedication and hard work of the Hispanics. You may ask how will the Mixers accomplish their goal of becoming the only race in the world? By seducing the normal black and white person with their superior beauty. One mixed child at a time.
