People are inherently inequal. Every individual distinctively has a different intellectual and physiological disposition. Each individual has labored and exerted themselves in various ways for different ends. Each individual has different degrees of moral and ethical consciousness and regard. Each individual has inherently different implications in reception based on their genetic physiological form which is the accumulation of their genetic heritage. Each individual receives and interprets knowledge differently based on their degree of education, self discipline, and comprehension. Your misconception is in the belief in "intrinsic" value. Value is predicated on the human objective, condition, and social standards. Humans in themselves have no value inherently; the basis of your objection is simply flawed. In every aspect of the various metrics of worth, there is subjectivity. Where there is subjectivity or skill, there are degrees. Humans are liable to be categorized by these degrees. In my perspective, I look less at origin, and more at the offset of their current condition, thus your attribution of a genetic implication is also flawed under my metric, and fails to address the subject matter.
