"PLESSY VS. FERGUSON: THE MEANING OF THE ONE-DROP RULE
...
Homer Adolf Plessy purchased a ticket from New Orleans to Covington and took a seat in the white section of the East Louisiana Railroad Company train. Railroad officials ordered Plessy to the colored car. When he refused, a police officer forcibly ejected Plessy and hurried him off to the parish jail in New Orleans. Officials charged Plessy with violating a recently enacted state lawone of many Jim Crow laws enacted in the late 1800s as whites moved to entrench their power in state governmentsthat barred persons from occupying rail cars other than those to which their race had been assigned.
Had railroad officials not been notified in advance that Homer Plessy was one-eighth black, he undoubtedly could have taken his seat in the white section of the train. Plessy appeared to be white. Louisiana, however, applied the one drop rule: anyone with one drop of non-white blood was classified as colored under the Louisiana code. Plessy gave up the privilege that he might have enjoyed as the result of his light pigmentation because he shared the goals of the Citizens Committee to Test the Constitutionality of the Separate Car Law, a New Orleans group of blacks and Creoles. The Committee believed that a white-appearing plaintiff such as Plessy might be more likely to obtain the sympathy of a court reviewing the Louisiana law.
If found guilty, Plessy faced a possible fine of $25 and a sentence of up to twenty days in jail. Plessy challenged the Louisiana Separate Car Law, arguing that it violated the Fourteenth Amendments guarantee of equal protection of the laws. In October of 1895, the United States Supreme Court heard Plessys arguments.
The Court upheld Louisianas Separate Car Law in the case of Plessy v. Ferguson. In so doing, it announced the legal principle, separate but equal, that would guide American race relations for over half a century. Justice Henry Browns opinion, reflecting no understanding of racial realities in America, reads as though written by a Martian: The underlying fallacy of plaintiffs argument consists of the assumption that the enforced separation of the two races stamps the colored race with a badge of inferiority. If this be so, it is not by reason of anything found in the act, but solely because the colored race chooses to put that construction on it. John Marshall Harlan offered a lone dissent. Justice Harlan, in a ringing passageone suggested in a brief filed by Plessys lawyer, Albion Tourgeeargued our Constitution is color-blind, and neither knows nor tolerates classes among citizens. In respect of civil rights, all citizens are equal before the law.

A phony separation enforced by the label "caucasion" isn't any different from putting people in another train car because you think they are less than you.
