If the first duty of a free person is not to insure that all share that freedom, then what do you see as the first duty of those who live in free countries?
It is our first duty to uphold the law and the law says that we are all equal under the law of the land.
The duty of all citizens, first and foremost is to insure as best as one can that the law is followed. That is why we can all make a citizens arrest.
If you see someone’s freedom being supressed and do not act, you are not doing your duty and that is not honorable.
