Reading some stuff about eugenics online tonight an amusing thought popped to mind. Many modern fans of the concept are racist booboos who think their particular ethnic group or skin colour is the most wonderful one of them all, and hence must be preserved, its genetics unsullied by combining with other supposedly inferior groups. But if one were to be truly eugenic one would have to advocate mating the most "suitable" humans for whatever trait you were trying to enhance, regardless of their supposed race. In other words engage in the "race mixing" that drives these kind of people up the wall. After all if one wants to maximise intelligence via eugenics then a white woman with a genius level IQ should be mating with others of that level of IQ, even if they're black, or Asian, or whatever.
