Political Rhetoric, 1880
Irrational, unreasonable and outdated biological survival instinct derived from the wariness of infectious diseases, carried by strangers, easily spread to other populations without immunity. A racist social construct.
Contrasted with “xenomania” and “xenophilia” in the London Daily News around 1880 — before it was a synonym for “racist” — the term was first used to describe a fear of “foreigners” or “the Other”, similar to agoraphobia, in 1903 repetitively in The Nation. It has no basis in science or medicine.
