"Opponents of the black reparations effort have two common arguments against it: slavery happened too long ago, and not all white Americans have slave-owning ancestors. Similar arguments are now commonplace“ . What does this mean?

Racist  

Explanation:

For the first time, most major Democratic presidential contenders are talking about whether the U.S. government should consider paying reparations to the descendants of African Americans who were enslaved and suffered from large-scale racial discrimination. At least three of these candidates, Sen. Cory Booker of New Jersey, former San Antonio Mayor Julián Castro and Sen. Elizabeth Warren of Massachusetts, support the creation of a commission that would study the impact of slavery and the Jim Crow discrimination against black Americans that continued after emancipation. The commission would make recommendations about how to compensate black Americans for those injustices.

The question of whether the U.S. government should compensate the descendants of enslaved and oppressed African Americans has never gotten this much attention. Even former President Barack Obama deflected this concept while he was in the White House.
