The correct answer is resistance.
Resistance is a term in psychoanalysis that refers to the phenomenon where individuals or clients in therapy are unwilling to discuss an issue or talk about their feelings. In order to resist intervention and facing painful feelings and emotions, individuals exhibit behaviors such as Bruce's- arriving late for therapy, missing appointments and making small talk with his therapist.
The Radical Republicans took several different steps to make Reconstruction harder for the white South including:
1) Development of the Freedmen's Bureau- This federal agency was made to ensure that African-American citizens were having their constitutional rights protected. This meant that white Southerners could not enslave these individuals anymore.
2) Reconstruction Acts- These laws helped to organize the former Confederacy into different military zones that were monitored by the federal government.
3) Constitutional Amendments- Radical republicans allowed African-American men the right to vote and outlawed slavery in its entirety, breaking down the oppressive system set up by white Southerners.
I believe its the natural party, but I may be wrong.
