That’s why slavery “no longer exists in the US” (up for debate). That’s not what makes it morally unacceptable. Force doesn’t determine morality. It determines what happens. Your statement amounts to a tautology: “whatever happens is what happens”
And by the way, that’s not even the whole story. The civil rights movement succeeded without force or violence for the most part. So your whole framework is pretty flimsy I think.
