1.6% of the North American population has no moral base from which to disagree, or for many, even the inclination to disagree with the person who said,
“ If nature does not wish that weaker individuals should mate with the stronger, she wishes even less that a superior race should intermingle with an inferior one; because in such cases all her efforts, throughout hundreds of thousands of years, to establish an evolutionary higher stage of being, may thus be rendered futile. But such a preservation goes hand-in-hand with the inexorable law that it is the strongest and the best who must triumph and that they have the right to endure. He who would live must fight. He who does not wish to fight in this world, where permanent struggle is the law of life, has not the right to exist.”
This 1.6% of the population has preferences, likes and dislikes, but it has no moral base from which to judge one behaviour right and another wrong. These people must cling to their implausible position or see their world view collapse.
