Humans really are just skin-deep: "Buddy, it's just skin. Whether it's on my hands or my shoulder blades, it's still only dermal. Whether it's the new mocha or the old speckled white, it's still just presidential skin."
No. It really isn't. It's a collection of experiences. A background. A heritage. He grew up differently than a white kid. With racism and the knowledge that if he'd been born a hundred and fifty years earlier, he'd have been enslaved by whites. It's growing up invisible to popular media (how many black faces did you see on TV before the Jeffersons?) It's growing up afraid of the police. It's growing up with a different culture in the same society.
It's not just skin.
