Personhood is always redefined to exclude the intended victim class.
In 1935, the Nuremberg Laws codified the exclusion of Jews from German society. The next year, the Reichsgericht (Germany's highest court) essentially legalized the Holocaust. Cartoons routinely depicted Jews as pigs, dogs, rats, and other vermin.
In 1857, the U.S. Supreme Court declared Blacks "...a subordinate and inferior class of beings..." in
[Dred] Scott v. Sandford. Black slaves were often assigned diminutive names, such as "Mingo," that were normally reserved for pets.
In 1973, the U.S. Supreme Court found that "the word 'person,' as used in the [Constitution], does not include the unborn." Today, unwanted children are spoken of in dehumanizing terms: "embryo," "fetus," "products of conception," etc.
