Question

1. why did most free african americans dislike the american colonization societys plan for black migration to africa?

they feared that they would be forced into slavery.
they were already treated as equals in northern society.
they were afraid they would lose the right to vote.
they had been born in the united states and considered it home.

Explanation:

Most free African Americans had been born in the United States and saw it as their home. They did not want to be uprooted and sent to a continent they had no connection to in terms of their lived experience. The idea of being "returned" to Africa was not in line with their sense of identity and belonging in the US. Also, they were not treated as equals in Northern society (so that option is incorrect), there was no real fear of forced slavery in this context (as the plan was for emigration, not enslavement), and losing the right to vote was not the main reason for their dislike (as the core issue was about their connection to the US as their home).

Answer:

They had been born in the United States and considered it home.
