No. In the history of America, biracials have always existed, as slave owners routinely raped their female slaves. This led to many biracial kids being born. Now some white men sold their biracial kids in to slavery for cash, while others actually treated their kids as human and trained them and sent them off to school. As a result many biracials with rich parents actually schooled in Europe in the 1800s, becoming doctors, lawyers, and other professionals. The french white people were big on this, which led to the creation of the creole population in Louisiana.
