That's why this feels familiar! We've been here before--
On Dec. 12, 1912, Rep. Seaborn Roddenberry (R-Ga.) proposed this amendment to the Constitution:
'Intermarriage between negros or persons of color and Caucasians . . . within the United States . . . is forever prohibited.'
The amendment did not pass, even though the majority of Americans opposed interracial marriage and advocates argued this amendment was necessary to save the sacred institution of marriage.
