And then in America they created a system based on a racial hierarchy therefore mastering the use of the race card.
"After “race” as a scientific term was first introduced by the French philosopher-scientist
Georges L.L. de Buffon in 1749, the term was expanded into a system for the classification of the varieties of humankind by Johan Friedrich Blumenbach in his book On the Natural Variety of Mankind written in 1775."
"The concept of race remained a method of simple classification for almost 60 years until it was transformed into a component of a scientific theory defending slavery in the southern part of the US."
The Scientific Theory of Racial Inequality
Faced with external and internal attacks and no longer able to defend slavery in the old way, the Southern ruling class came to rely on a new, stronger defense of the slave system. As John C. Calhoun proclaimed:
"It is not enough for the Southern people to believe that slavery has been entailed upon us by our forefathers. We must satisfy the consciences, we must allay the fears of our own people. We must satisfy them that slavery is of itself a right-that it is not a sin against God—that it is not an evil, moral or political. . . . In this way, and this way only, can we prepare our own people to defend their institutions."
Thomas R. Dew and William Harper responded to Calhoun’s call by uniting Buffon’s and Blumenbach’s system of classification with Aristotle’s defense of slavery:
“He is then by nature formed a slave who is fitted to become the chattel of another person, and on that account is so.” Thus, the “scientific” theory of the natural inequality of different groups of humans was born as a justification of slavery on the basis of racial inequality.
A history of the concept of race and science's role in its justification, originally featured in SftP's 1982 issue "Racism in Science."

All these men were white and they invented the race card. Then the made race a qualification for citizenship.
The Naturalization Act of 1790 states:
“any alien, being a free white person,” could apply for citizenship, so long as they lived in the United States for at least two years and in the state where the application was filed for at least one year. This law allowed “children of citizens of the United States that may be born … out of the limits of the United States shall be considered as natural-born citizens.” Please notice the first seven words. Only whites were entitled to be citizens of this country.
That's playing the race card and whites have played it since the initial founding of this country. Whites perfected it by a series of supreme court rulings most notably Dred Scott v. Sandford and Plessy v. Ferguson. History is documented opinions and beliefs have no place in this discussion. I said whites invented the race card because documentation shows that IS what happened.
