Well, to start, genocide is a systemic and organized killing of a targeted group. White people are still the majority of the United States population, and there is no evidence of Jews or any other group carrying out a genocide against Caucasians. Moreover, diversifying the population, which might result in more interracial relationships and biracial children, has nothing to do with genocide. How could it be genocide if no-one is dying and it is free love? It also doesn't erase any race; e.g. a child with a white mother and a Latino father is as much white as they are Latino.
