What started out as a debate between two young brothers about if they were brown or black became a lesson on race.
Theo and Uria asked their dad, Glen Henry, whether they were black or brown. Henry stepped in to bring some clarification to the conversation.
After a gasp, Theo asked, “So why are we black people?”
Henry then shows Theo and Uria a photo of them with their friends, all with varying shades of skin, and explains what melanin is.
“When you see other black people ... he’s a black person, too,” the dad explained. “We are black people, but our skin is brown.”
When Theo mentioned one of his white friends, Henry told the boys: “Just because our skin is different, doesn’t mean we are different people; we just have different color skin.”
“No matter what color the skin is, you can still be friends with everybody. We are all friends,” Henry said. “Everybody’s equal.”
