What was slavery in America, and why was it wrong?

Some questions are heavy, and this is one of them. Slavery in America is not a fun story, and pretending it is would be a kind of lie. But it's an important story — one worth understanding clearly, told gently, and finished with hope. So let's walk through it together, slowly.
First, what does the word even mean? To be enslaved means a person is treated as if they are property — something to be owned, bought, and sold, like a chair or a horse. But people are not chairs. Every person has their own thoughts, their own family, their own name they were born with. That gap — treating a someone like a something — is the whole tragedy in a single sentence.
