As previously mentioned, here's what Einstein had to say about segregation:

"There is a separation of white people and colored people in the United States. That separation is not a disease of colored people. It is a disease of white people. I do not intend to be quiet about it."

For the last 20 years of his career, Einstein declined almost all public speaking engagements, except those at Historically Black Colleges and Universities (HBCUs).
