Civilization has always been been influenced by various forms of discrimination. Even in modern America, where we like to believe that most types of discrimination have been dispelled, we are regularly reminded that some of the worst remain. Some forms of discrimination get recycled and reassigned, as if they will be more tolerable if applied to more appropriate victims.
Society can be rather discriminating about who it discriminates against.
People of African descent have always been discriminated against in America. Racists who justify such discrimination might consider them collectively to be more innately prone to thievery, as well as violence, vandalism, addiction, exploitation of social services, and any other social transgression that imaginative racists can conceive. It is what justifies racism and discrimination.
Historically, people of Asian descent, particularly Chinese descent, were collectively considered by racists to be more innately prone to addiction (to opium), as well as thievery and squalorly lifestyles. For a disgraceful period of American history, people of Japanese descent were incarcerated merely because they were racially related to enemies of America during World War II.
Many racists still consider Indigenous People of North America to collectively be more innately prone to alcoholism, as well as the many other transgressions that people of African and Asian descent are similarly blamed for. It is a common and typical pattern of racism and discrimination. Behavior that should be attributed to environment is instead attributed to genetics, or race.
It is easy enough to find pictures or other documentation of people conforming to the stereotypes of their respective racial designation. ‘Nature versus Nurture’ need not be mentioned if the objective is to justify racism and discrimination; although disproportionate conformation typically is mentioned. Justification of racism and discrimination rarely involves the use of any logic.
Now that racial discrimination is very slowly becoming less socially acceptable among common American society, some of those who might otherwise be racist are directing more unfounded hostility to other groups, such as those who are wealthier or more impoverished, including the homeless. Because this sort of discrimination is not racist, society is slightly more tolerant of it.
However, modern American society is realizing that unfounded discrimination against some of the homeless is merely a different flavor of the same recycled racial discrimination that is now so stigmatized. The irrational hostility and lack of logic eventually make it obvious. We have seen it all before, continue to see it, and sometimes see it in initially unrecognizable incarnations.
