Historically, various philosophies have faced opposition from white people, often depending on the specific context, time period, and the particular group of white people involved. However, one notable example is:

• Pan-Africanism: This philosophy promotes the idea of a unified African identity and solidarity among people of African descent worldwide. It seeks to strengthen bonds between all indigenous and diasporic Africans.

• Colonial Era: During the height of European colonialism, Pan-Africanism was seen as a threat to colonial powers. It challenged the legitimacy of European control over African territories and resources. White colonial administrators and settlers actively suppressed Pan-Africanist movements and ideas.
• Segregation and Civil Rights Era: In the United States and other countries with significant populations of African descent, Pan-Africanism was often viewed with suspicion by white authorities and some segments of the white population. Its emphasis on racial solidarity and self-determination was seen as a challenge to the existing racial hierarchy.

It is important to note that not all white people opposed Pan-Africanism, and some even supported it. However, historically, it has faced significant opposition from those who benefited from or sought to maintain white dominance and racial inequality.
