I'll be honest, I don't get why people get so hung up on this Animals still existing alongside animal-people thing.

I mean it's like an alien watching a show about Earth and saying "Why does this world have chimps and bonobos when the world has Humans!"

So Goofy's from a species of dog that became a dog-person, while Pluto's from a species of dog that remained a dog. Just like how Humans are apes that became people, while chimpanzees are apes that remained apes.

Simple as. So what's the big hold up?

The first actual Black slave in the colonies that would later become the USA was owned by a Black guy.
