I think she is reflecting in her theorising , the centrality given to skin colour by the elites controlling the European narrative relating to racially based hierarchies. So she analyses this obsessive need to prove superiority by the marauding Europeans when they realised that their genotypes were recessive and so sex with women of Asian / African etc herding rage usually meant dark eyes and darker skinned offspring , thus erasing the European demarcations. She is such an original thinker, stepping outside the self- promoting narratives that continue to prevail in the so called social sciences !
