What does this recollection by John McCoy suggest as a reason for the failure of efforts to guarantee freedmen full citizenship rights?

John McCoy's recollection suggests that the failure to guarantee full citizenship rights to freedmen was largely due to deep-seated racism and resistance from white society. Despite the legal framework established during Reconstruction, societal attitudes and systemic discrimination undermined these rights. The lack of political will and support from both government and communities made it challenging to enforce protections for freedmen, leading to ongoing marginalization. Ultimately, McCoy's experience highlights the gap between legal rights and social realities for African Americans during this period.
