Why did most free African Americans dislike the American colonization societys plan for black migration of Africa?

Most free African Americans opposed the American Colonization Society's plan for black migration to Africa because they viewed it as a form of racial separation and an implicit rejection of their rights as American citizens. Many free blacks felt a strong connection to the United States and believed they had the right to live freely and fully participate in American society. Additionally, the plan was seen as an attempt to rid the country of its black population rather than addressing the systemic issues of racism and inequality that they faced.
