I know of a white teacher who graduated from school in about the 1970’s and insisted on teaching in a black school. She wanted to help black students. One of her students was failing badly and she wanted the child to repeat his grade.
When the student’s mother complained to the black principal, the teacher was threatened with dismissal.
The student was promoted to the next grade without having learned enough.
The teacher had learned her lesson. She transferred to a white school.
To help make up for the disparity, politicians created Affirmative Action — another Liberal failure.
