I don't think you're qualified to attempt to teach anyone anything on this particular subject since you seem to be woefully unaware of what white America defines as a "Black person" or person of African descent:
One-drop rule
The
one-drop rule was a
legal principle of
racial classification that was prominent in the 20th-century United States. It asserted that
any person with even one ancestor of black ancestry ("one drop" of "black blood")[1][2] is considered black (Negro or colored in historical terms). It is an example of
hypodescent, the automatic assignment of children of a mixed union between different socioeconomic or ethnic groups to the group with the lower status, regardless of proportion of ancestry in different groups.
[3]
This concept became codified into the law of some U.S. states in the early 20th century.
[4] It was
associated with the principle of "invisible blackness"[5] that developed after the long history of racial interaction in the South, which had
included the hardening of slavery as a racial caste system and later segregation. Before the rule was outlawed by the Supreme Court in the
Loving v. Virginia decision of 1967,
it was used to prevent interracial marriages and in general to deny rights and equal opportunities and uphold white supremacy.
Antebellum conditions
Before the American Civil War, free individuals of mixed race (free people of color) were considered legally white if they had less than either one-eighth or one-quarter African ancestry (only in Virginia).[6] Many mixed-race people were absorbed into the majority culture based simply on appearance, associations and carrying out community responsibilities. These and community acceptance were the more important factors if a person's racial status were questioned, not their documented ancestry.
Based on late 20th-century
DNA analysis and a preponderance of historical evidence, US president
Thomas Jefferson is widely believed to have fathered the six
mixed-race children with his slave
Sally Hemings, who was herself three-quarters white and a paternal half-sister of his wife
Martha Wayles Jefferson.
[quote 1] Four of them survived to adulthood.
[7] Under Virginia law of the time, while their seven-eighths European ancestry would have made them legally white if they'd been free, being
born to an enslaved mother made them automatically enslaved from birth. Jefferson allowed the two oldest to escape in 1822 (freeing them legally was a public action he elected to avoid because he would have had to gain permission from the state legislature); the two youngest he freed in his 1826 will. Three of the four entered white society as adults. Subsequently, their descendants identified as white.
Although
racial segregation was adopted legally by southern states of the former Confederacy in the late 19th century, legislators resisted defining race by law as part of preventing interracial marriages. In 1895, in
South Carolina during discussion,
George D. Tillman said,
The one-drop rule was not formally codified as law until the 20th century, from 1910 in Tennessee to 1930 as one of Virginia's "racial integrity laws", with similar laws in several other states in between.

In 1911, Arkansas passed Act 320 (House Bill 79), also known as the “one-drop rule.” This law had two goals: it made interracial “cohabitation” a felony, ...
