You know what real racism is because you do it. Stop trying to tell somebody black how they don't know what real racism is, as if real racism is only the type that went on during Jim Crow. White racists have always adapted their racism to fit the rules. When slavery encded, white rcists created Jim Crow. When Jim Crow ended, we see what is called Laissez Faire Racism
“Laissez-Faire Racism involves persistent negative stereotyping of African Americans, a tendency to blame blacks themselves for the black-white gap in socioeconomic standing, and resistance to meaningful policy efforts to ameliorate America’s racist social conditions and institutions.”
