Modern racism reframes race struggle as a society threatened from within by outsiders.

Evidence

Second, society is no longer seen through a binary prism, instead it is approached as a whole “threatened by a certain number of heterogenous elements which are not essential to it … hence the idea that foreigners have infiltrated this society” (Foucault, 1997, p. 81). At this point racial discourse took over and reworked the race war discourse, and then the idea of “race purity replaces that of race struggle.” — Sarah Bracke and Luis Manuel Hernández Aguilar, “They Love Death as We Love Life”, 306

Categorization

• DEEPTHINKING: The pivot from binary war between races to a whole society menaced by infiltrators is the exact mechanism by which demographic panic becomes biopolitical rather than merely hostile.
• XREF: Links to Foucault’s biopower/state racism lectures and to Zamyatin’s We as a fictional treatment of purity versus heterogeneity.
