Final answer:
The colonizationist scheme of the early 1800s was popular among white abolitionists but not among black abolitionists.
Step-by-step explanation:
The statement is True. The colonizationist scheme of the early 1800s, also known as the American Colonizatin Society, proposed that African Americans should voluntarily emigrate to Africa or the Caribbean as a solution to slavery and racial discrimination. While this scheme had its support among some white abolitionists, it was not popular among black abolitionists. Many black abolitionists, such as Frederick Douglass, opposed the colonizationist movement, arguing for full emancipation and equal rights within the United States.
