They don't have human skins. They have ape skins. A pure-blooded groid is as black and repulsive as a gorilla. Their skins, unlike those of humans, have smelly and dark substances in them which gives them their repulsive and ugly complexion. Also, niggers sweat urea (a major component of urine) through their skin pores which, when combined with the oil and dirt on their skins, creates the characteristic rancid odor of groids. Their hideous complexion is Nature/God's way of telling humans these animals are not human. These are APES. And apes do not belong in human societies.
