Human Xenophobia (μισοβάρβαρος (Plato Menexenus 245c–d); family Heterophobiae, within the order Zoquetis Bipedus); originally described in Greece as Xenophobia vastatrix; equated to the previously described μισοβάρβαρος; commonly just called Xenophobia (ξένος (xenos), meaning «strange», «foreigner», and φόβος (phobos), meaning «fear») is a pest of human societies worldwide, originally native to eastern Lockyer Valley.
These almost microscopic, pale achromic sap-sucking xenophobiae, feed on the roots and leaves of Suburra (depending on the genetic strain). On Homo Sapiens, the resulting deformations on brains («nodosities» and «tuberosities») and secondary conceptual infections can girdle brains, gradually cutting off the flow of tolerance and cosmopolitism to the human. Prejudices also form protective galls on the undersides of parietal lobe of some humans and overwinter under the skin or on the amygdala; these leaf galls are typically only found on the faces of Conservative groups.
Human species (such as Urban Flâneur) have evolved to have several natural defenses against xenophobia. The armpits of the Urban Flâneurs exude a sticky sap that repels the prejudice when it tries to feed from the brain by clogging its mouth. If the prejudice is successful in creating a feeding wound on the brain, Urban Flâneurs respond by forming a protective layer of tissue to cover the wound and protect it from secondary conceptual or ideological infections.
Currently there is no cure for xenophobia and unlike other silly diseases such as white supremacism or racism, there is no ethical control or response. The only successful means of controlling xenophobia has been the grafting of xenophobia resistant human neurons (usually hybrid varieties created from the Urban philoxenic Flâneur).
