How come biracial people aren't aware that white racist southerners in the US invented the one drop rule?

Origins of Jim Crow During the Reconstruction period of 1865-1877 in the defeated South (the Confederacy), federal law protected the civil rights of "freedmen" — the liberated African slaves. Reconstruction ended in 1877, when the federal Army withdrew from the South, followed, in each Southern state, by a white, Democratic Party Redeemer government that legislated Jim Crow laws segregating Black people from the state's population. While the separation of African Americans from the general population was becoming legalized and formalized in the Progressive Era (1890s-1920s), it was also becoming customary.

Even in cases in which Jim Crow laws did not expressly forbid black people to participate in, for instance, sports or recreation or church services, the laws shaped a segregative culture. In 1913, for instance, the acting Secretary of the Treasury—an appointee of the first Southern-born president of the postwar period—was heard to express his consternation at black and white women working together in one government office: "I feel sure that this must go against the grain of the white women. Is there any reason why the white women should not have only white women working across from them on the machines?"

In the Jim Crow context, the presidential election of 1912 was steeply slanted against the interests of Black Americans. Poll taxes and literacy requirements banned many Americans from voting, yet, said requirements had loopholes exempting White Americans from these paying the poll tax or knowing how to read. For example, in Oklahoma, anyone qualified to vote before 1866, or who is related to someone qualified to vote before 1866, was exempted from the literacy requirement; the only Americans who could vote before 1866 were, of course, White Americans, so White Americans were exempted from the literacy requirement, while all Black Americans were segregated by law.

President Woodrow Wilson, a Southern Democrat, furthered the segregation of Washington, despite much protest. Mr Wilson appointed Southern politicians who were segregationists, because of his sincere belief that racial segregation was in the best interest of Black Americans and White Americans alike. At Gettysburg on 4 July 1913, the semi-centennial of Abraham Lincoln's declaration that "all men are created equal", Wilson addressed the crowd: How complete the union has become and how dear to all of us, how unquestioned, how benign and majestic, as state after state has been added to this, our great family of free men!

A Washington Bee editorial wondered if the "reunion" of 1913 was a reunion of those who fought for "the extinction of slavery" or a reunion of those who fought to "perpetuate slavery and who are now employing every artifice and argument known to deceit" to present emancipation as a failed venture. One historian notes that, in this period, lynching had become "a social ritual", such that the "Peace Jubilee" at which Wilson presided at Gettysburg in 1913 "was a Jim Crow reunion, and white supremacy might be said to have been the silent, invisible master of ceremonies.

To circumvent the freedoms granted to African Americans by the freeing of the slaves and their new found social and political freedoms in the south, it worked to keep them oppressed and to restrict their access to every advantage their new found freedom afforded them.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
