I have it on a higher authority.
Scott v. Georgia (1869): "The amalgamation of the races is not only unnatural, but is always productive of deplorable results. Our daily observation shows us, that the offspring of these unnatural connections are generally sickly and effeminate [...]They are productive of evil, and evil only, without any corresponding good."
Bob Jones University, (1998): "Although there is no verse in the Bible that dogmatically says that races should not intermarry, the whole plan of God as He has dealt with the races down through the ages indicates that interracial marriage is not best for man."
Scott v. Sandford (1857), Chief Justice Taney: "Intermarriages between white persons and negroes or mulattoes were regarded as unnatural and immoral."
Senator James R. Doolittle (D-WI), 1863: "By the laws of Massachusetts intermarriages between these races are forbidden as criminal. Why forbidden? Simply because natural instinct revolts at it as wrong."
Lonas v. State (1871): Attorneys argued that intermarriage was "distasteful to our people, and unfit to produce the human race in any of the types in which it was created." Tennessee's court agreed, saying that "any effort to intermerge the individuality of the races as a calamity full of the saddest and gloomiest portent to the generations that are to come after us."
State v. Jackson. Missouri (1883): "They cannot possibly have any progeny, and such a fact sufficiently justifies those laws which forbid the intermarriage of blacks and whites."
Virginia's Racial Integrity Act of 1924: The law's stated purpose was to prevent "abominable mixture and spurious issue." It "forbade miscegenation on the grounds that racial mixing was scientifically unsound and would 'pollute' America with mixed-blood offspring."
From a submitted briefing to the Court on Loving v. Virginia: "I believe that the tendency to classify all persons who oppose [this type of relationship] as 'prejudiced' is in itself a prejudice," a psychologist said. "Nothing of any significance is gained by such a marriage."
Do you get it from the same higher authority as these people?
