Douglass said, "the words "privileges and immunities" comprehend all the rights ... which belong to a person in a state of civil society". (He didn't say, "the words "privileges and immunities" comprehend all the rights ... which belong to a Citizen of a state.) I listed a whole bunch of those belonging to a person in a state of civil society in an earlier post.
