The ruling was final. It was by the highest court in the land. Well, you don't have to own a slave, but don't impose your morality on the slave owner. He has the right to choose to own a slave. The Supreme Court has spoken.
Slavery is legal.
But not for long. It took a bloody civil war to stop slavery. It took the 13th, 14th, and 15th Amendments to the Constitution to legally grant freedom, civil rights, and voting rights. From a socioeconomic view, we are still striving for full equality. This could be done at any time until birth.
