Legislation on the subject of marriage is clearly inside the province of government. That such an argument as is quoted from William Lloyd Garrison can still be circulated in the United States and apparently carry weight, is sufficient cause for one to feel pessimistic over the spread of the scientific spirit in this nation. Suffice it to say that on this point the National Association is a century behind the times. The following policy seems to us to be in accordance with modern science, and yet meet all the legitimate arguments of the National Association. We will state our attitude as definitely as possible: 1. We hold that it is to the interests of the United States, for the reasons given in this chapter, to prevent further Negro-white amalgamation. 2. The taboo of public opinion is not sufficient in all cases to prevent intermarriage, and should be supplemented by law, particularly as the United States have of late years received many white immigrants from other countries (e. g., Italy) where the taboo is weak because the problem has never been pressing. 3. But to prevent intermarriage is only a small part of the solution, since most mulattoes come from extramarital miscegenation. The only solution of this, which is compatible with the requirements of eugenics, is not that of _laissez faire_, suggested by the National Association, but an extension of the taboo, and an extension of the laws, to prohibit all sexual intercourse between the two races. Four states (Louisiana, Nevada, South Dakota and Alabama) have already attempted to gain this end by law. We believe it to be highly desirable that such laws should be enacted and enforced by all states. A necessary preliminary would be to standardize the laws all over the Union, particularly with a view to agreement on what a "Negro" legally is; for in some states the legislation applies to one who is one-sixteenth, or even less, Negro in descent, while in other states it appears to refer only to full-blood or, at the most, half-blood individuals. Such legislation, and what is more important, such public opinion, leading to a cessation of Negro-white amalgamation, we believe to be in the interests of national eugenics, and to further the welfare of both of the races involved. Miscegenation can only lead to unhappiness under present social conditions and must, we believe, under _any_ social conditions be biologically wrong. We favor, therefore, the support of the taboo which society has placed on these mixed marriages, as well as any legal action which can practicably be taken to make miscegenation between white and black impossible. Justice requires that the Negro race be treated as kindly and considerately as possible, with every economic and political concession that is consistent with the continued welfare of the nation. Such social equality and intercourse as might lead to marriage are not compatible with this welfare. CHAPTER XV IMMIGRATION
