Racist ideas make people of color think less of themselves, which makes them more vulnerable to racist ideas. Racist ideas make White people think more of themselves, which further attracts them to racist ideas.
And I've come to see that the movement from racist to antiracist is always ongoing it requires understanding and snubbing racism based on biology, ethnicity, body, culture, behavior, color, space, and class.
Like fighting an addiction, being an antiracist requires persistent self-awareness, constant self-criticism, and regular self-examination.
Some White people do not identify as White for the same reason they identify as not-racist: to avoid reckoning with the way that Whiteness--even as a construction and mirage--has informed their notions of America and identity and offered them privilege, the primary one being the privilege of being inherently normal, standard, and legal.
