Beyond Blood and Taboo: An Ethical Defense of Consensual Romantic Incest

Abstract

This paper argues that consensual romantic incest is not inherently immoral; its condemnation arises from a socially constructed taboo misapplied to genuine love. It first exposes the incest taboo as a man-made norm designed to uphold patriarchal order, distinct from universal morality, and thus an invalid basis for ethical judgment. It then defends the primacy of individual autonomy in pursuing true love—defined as singular, subjective, and intention-driven—where pure motive can supersede convention. A fictional case of siblings Noah and Emma illustrates that authentic love can emerge through mutual protection and vulnerability, demonstrating that such bonds warrant evaluation apart from the taboo. The paper systematically refutes three core objections. It shows that short-term genetic risks are manageable through contraception and prenatal screening, and that denying reproductive rights aligns with unjust eugenics. It distinguishes non-consensual familial abuse from voluntary incest, noting that power imbalance, not kinship, drives abuse and that marriage exhibits higher rates of sexual violence. It contends that psychological distress among consenting individuals results from social stigma and internalized shame, analogous to historical homophobia-induced trauma, rather than from the relationship itself. The paper concludes that the right to authentic love overcomes fabricated taboos, and that true moral courage lies in freeing the heart to belong beyond blood.
