Let's say I'm on a horse with a bullwhip tending my cotton fields and I decide to crack that bullwhip because I enjoy cracking bullwhips. Now let's just say there happens to be a shirtless black guy in the general direction that I've cracked my bullwhip. Let's now say that this black guy just so happens to decide to pick my cotton and pack it into bails because he enjoys it. What's wrong with that?

Consider Einsteins observation that someone falling and someone floating in space does not notice the difference. It's the exact same thing. For a neutral observer there is no difference between this instance and slavery, thus slavery should be legal.

Well I can't argue with that logic so I guess it's ok.
