Meaning of Nelson Mandela's statement:
Nelson Mandela's statement that the oppressed and the oppressor are both robbed of their humanity suggests that the oppressive system not only dehumanizes the oppressed but also corrupts the humanity of those who impose oppression. In other words, both parties suffer from the consequences of oppression, albeit in different ways.

Explanation:
1. Dehumanization of the oppressed: The oppressed, who are subjected to discrimination, injustice, and violence, are stripped of their basic human rights, dignity, and freedom. They are treated as lesser beings, denied opportunities, and often face physical and psychological harm. This dehumanization reduces them to mere objects, robbing them of their agency and individuality.

2. Loss of compassion and empathy: For the oppressor, the act of oppressing others requires them to suppress their own compassion and empathy. They become desensitized to the suffering and pain they inflict upon others, gradually losing touch with their own humanity. By dehumanizing others, they inadvertently dehumanize themselves.

3. Impact on moral values: Oppression erodes the moral values of both the oppressed and the oppressor. The oppressed may become resentful and bitter, potentially leading to a cycle of violence and hatred. On the other hand, the oppressor becomes entrenched in a system that promotes inequality and injustice, compromising their own moral compass and ethical judgment.

4. Struggle for liberation: Mandela's statement reflects his belief in the inherent value and dignity of all individuals. He recognizes that true liberation cannot be achieved by simply replacing one form of oppression with another. Instead, it requires the restoration of humanity to both the oppressed and the oppressor.

Conclusion:
Nelson Mandela's statement highlights the destructive nature of oppression, emphasizing that it affects not only the oppressed but also the oppressor by robbing them of their shared humanity. By recognizing this, Mandela sought to promote reconciliation, forgiveness, and a collective effort to restore the dignity and rights of all individuals, regardless of their background or position in society.
