And I read your response to imply that only one side of the equation has any rights. I submit that you are wrong on that.
The right to stop people from leaving? No, I don't think anyone has that right, or should.
The right to demand reparations? To demand punishment for offenses against them? The right to use force in the Defense against or punishment of others who wronged them? Sure.
But these rights cease once their goals have been met. Anything else goes beyond rights.
