As I white male, I can offer a simple explanation. You see the Apollonian and Dionysian instincts of all males were once dominant in the psyche of post-modernist males leading to a bifurcation and transference of basic erotic impulses. So when the preference of men with phallic melanism for labial albinism is manifested, it may include trans-generational proclivities. Interestingly, there may be a reflexive response on the part of said individuals manifesting labial albinism that complements the individuals with phallic melanism who may introduce genetic vigor in subsequent cohorts. Of course, this is conceptualized in Haeckel’s Law that ontogeny recapitulates phylogeny and is confirmed by the philosopher, Popeye’s credo that, “I yam what I yam.” This should answer the question.
