Grokipedia’s entry on the slogan argues that it “articulates a principle positing that ethnic groups possess an innate imperative to ensure their own continuity and reproduction against threats of assimilation, displacement, or extinction”.
The entry continues: “This view draws from observations in evolutionary biology, where kin selection and inclusive fitness mechanisms favor behaviors that propagate shared genetic lineages within closely related populations, extending individual self-preservation instincts to group-level survival strategies.”
Those who have associated the slogan with racial hatred, the entry argues, “exhibit patterns of selective scrutiny” or have “ideological priorities favoring certain victim narratives”.
