Why Justice Harlan does disagree with the principle of separate but equal?

Justice Harlan disagreed with the principle of "separate but equal" because he believed it inherently perpetuated racial discrimination and inequality. In his dissent in Plessy v. Ferguson, he argued that the Constitution is colorblind and should not tolerate any form of racial segregation, as it undermines the fundamental rights and dignity of individuals. Harlan recognized that separate facilities could never be truly equal, as they would foster a sense of inferiority among marginalized groups. His perspective emphasized the need for genuine equality and the moral obligation to reject segregationist policies.
