"We have a right, also, in various ways, to act upon our unfavorable opinion of anyone, not to the oppression of his individuality, but in the exercise of ours"

John Stuart Mill is suggesting that we deserve to express our viewpoint of someone, even if it is undesirable. However, we should not utilize this opinion to oppress the person, but rather to exercise our own rights. This means that we ought to not utilize our opinion to restrict the person's liberty or to deny them their rights. Instead, we ought to use our opinion to express our own beliefs and values. We ought to not use our opinion to manage or manipulate the individual. We must use our viewpoint to express our own views and to engage in meaningful dialogue with the individual. This permits us to reveal our opinion without infringing on the person's rights or flexibility.
