146 years ago today on March 6, 1857, SCOTUS ruled in Dred Scott v. Sandford that Black people were not not citizens, were subhuman, & could not sue in U.S. courts. Experts and historians point to this decision as the final straw that ignited the Civil War.

Sadly, throughout American history—from Dred Scott to Plessy to Korematsu to Nestle—SCOTUS has consistently prevented racial, gender, and economic progress.

And I'm afraid most people aren't aware of this because it isn't taught in schools.
