I take it as a good thing and as a measure of meaningful progress that white people absolutely lose their minds when someone suggests that they are racist.
After all, it wasn’t that long ago that a disturbingly large segment of America’s white citizens was unabashedly proud of their racist identity. It was an explicit expression of their superiority, intellectually, culturally, economically and politically, over people of color. In 1972 and 1976, George Wallace ran for president as a Democrat and won several state primaries each time. This is the same man who passionately declared, “Segregation now, segregation tomorrow, segregation forever!”
