Yes, it is entirely genetic. Look at a pit bull and a chihuahua and a labrador retriever. Do you believe that they are identical in disposition and abilities? Keep in mind, the caninie species were created in far fewer generations than the different subspecies of humans. Now, environment could play a role, as allowing the negroes to come into our society, and sink or swim on their own merits, would eventually result in the survivors adapting to theie environment. Unbfortunately, huans interferd with the process, and by supporting those incapable of surviving in our society, we would up with large numbers of unassimilable monkeys. I believ that we should help the niggers evolve, by rounding up all of the dumbest ones, and gassing them. If we get rid of the 75% of them with IQs below 90, we would speed up evolution by thousands of years.
