you sound like a dumbass redneck using genetic determinism to justify your racism

sorry but environment is not only important but actually the prevailing factor in many aspects of life like in the development of certain diseases and certainly in the development of one's full potential, whereas genes outside of phenotypical aspects are mostly related with propensity, which is the point your professor was trying to make

the fact that you fail to grasp this is laughable, the difference between the "full potential" of differente races is diminute, what matters is assuring everyone gets the opportunity to achieve it thus creating a harmonious and self-realized society

instead we have dumbasses like you that think because black people have a marginally inferior mean IQ they all belong in some kind of inferior caste, that they should all recognize this scientific reality and behave accordinglyand submissively and thank white people for taking them out of africa in the first place, when in reality IQ isn't a determining factor of success, isn't relevant to social adjustment and nobody gives a shit about it except racist rednecks that think they are cut out for university when they are so completely incapable of critical thinking they can't even identify the racist underpinnings moving their intellectual "pursuits"
