"Democrats, the party of Slavery, Secession, Segregation and the KKK… fought against equality."
Would that Jim Crow Laws and Plessy never were; they are an indelible stain on American jurisprudence.
Some of Justice Harlan's dissent in Plessy v. Ferguson (1896):
The white race deems itself to be the dominant race in this country. And so it is, in prestige, in achievements, in education, in wealth, and in power. So, I doubt not, it will continue to be for all time, if it remains true to its great heritage, and holds fast to the principles of constitutional liberty.
But in view of the constitution, in the eye of the law, there is in this country no superior, dominant, ruling class of citizens. There is no caste here. 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. The humblest is the peer of the most powerful.
The law regards man as man, and takes no account of his surroundings or of his color when his civil rights as guarantied by the supreme law of the land are involved. It is therefore to be regretted that this high tribunal, the final expositor of the fundamental law of the land, has reached the conclusion that it is competent for a state to regulate the enjoyment by citizens of their civil rights solely upon the basis of race.
I am of opinion that the state of Louisiana is inconsistent with the personal liberty of citizens, white and black, in that state, and hostile to both the spirit and letter of the constitution of the United States. If laws of like character should be enacted in the several states of the Union, the effect would be in the highest degree mischievous.
Slavery, as an institution tolerated by law, would, it is true, have disappeared from our country; but there would remain a power in the states, by sinister legislation, to interfere with the full enjoyment of the blessings of freedom, to regulate civil rights, common to all citizens, upon the basis of race, and to place in a condition of legal inferiority a large body of American citizens, now constituting a part of the political community, called the 'People of the United States,' for whom, and by whom through representatives, our government is administered.
Such a system is inconsistent with the guaranty given by the constitution to each state of a republican form of government, and may be stricken down by congressional action, or by the courts in the discharge of their solemn duty to maintain the supreme law of the land, anything in the constitution or laws of any state to the contrary notwithstanding.
