So by your standard. Would Malcolm X today be consider black by you, since his mother was biracial? And if a black has any traces of white in them does that make them not black because if you go back up their family tree you're bond to find a white person and biracial person. Also you're neglecting the genetics part of the argument. When discussing genotypes and phenotypes certain genotypes and phenotypes, dominant over others you can never truly have half and half in you're genetics. When a dominant genotype and phenotype is introduce to a recessive genotype and phenotype the dominant gene will always rule over the recessive....but that doesn't mean the recessive gene isn't there in a small percentage.I know you're young, but don't play dumb. One black parent + Another black parent = A black child. Anything other than that equation isn't producing a black child. And its really simple to tell, usually, when a mulatto person is mulatto.
