Robin DiAngelo is the most gifted speaker and educator on American racism in the country.   She has a PhD in sociology and has spent years studying racism.  Social discrimination and privilege are both measurable, and the evidence is undeniable.   She says that racism is the water we swim in.   It's everywhere.   White supremacy is so prevalent, studies show that by the age of three years to four years old, every child in America knows, without being told directly, that it's better to be white.
