Answer:
It isn't fair. It's supporting racial segregation. Segregation in all isn't fair or equal. It was unconstitutional under the fourteenth amendment.
"No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws."
Segregation in public education is a denial of the equal protection of the laws.
