You are confused. A right is not assigned or need somebody else to "give" it to you. You born with it and in some cases you give it away with your consent. Nobody can give you the right for x. You have it.
Freedom is not right nor privilege. https://i.postimg.cc/cLvhR9RZ/darth-freedom.jpg
Privilege is given by others. We are born with rights. I think we agree on this. Slavery has been with humanity as long as there have been humans. It is very much still with us. And for the enslaved, this God given birth-right has been taken away. How do you tell the enslaved that they alone are responsible for their captivity or their freedom?
You still have not answered the question:
Should a freed slave consider freedom a "privilege" or a "right"?
The question is rhetorical. We both know that Freedom is a right, not a privilege. But who shall free slaves? This is where the State can and should assist. To protect these rights. Which is the essence of my point.
