Whether or not you believe in God, it has to be acknowledged that the commandments of the Abrahamic God promote eugenics.
Eugenics is the practice of preventing degeneracy. For example, marriage and the prohibition against incest are eugenic in purpose. Therefore any practice of "sexual liberation" that desecrates the institutions of marriage and family would be ANTI-EUGENIC. Feminism is anti-eugenic. Therefore feminism is evil and eugenics is good.
