Here are a few examples of how wise governments have dealt with the question of whom one should be allowed to marry:
“Sec. 1999. Intermarriage with a Negro, etc., Declared Void.
Hereafter it shall not be lawful within this state for any white person, male or female, to intermarry with any negro, Chinese, or any person having one fourth or more negro, Chinese, or Kanaka blood, or any person having more than one-half Indian blood; and such marriages, or attempted marriages, shall be absolutely null and void.”
