I do atypical work for a white person, which is that I lead primarily white audiences in discussions on race every day, in workshops all over the country. That has allowed me to observe very predictable patterns. And one of those patterns is this inability to tolerate any kind of challenge to our racial reality.

There's a lot of ways that white women undermine women of color, and black women in particular.

This is what I have learned: Any white person living in the United States will develop opinions about race simply by swimming in the water of our culture. But mainstream sources - schools, textbooks, media - don't provide us with the multiple perspectives we need.

For a lot of white people, just suggesting that being white has meaning will trigger a deep, defensive response. And that defensiveness serves to maintain both our comfort and our positions in a racially inequitable society from which we benefit.

A fundamental but very challenging part of my work is moving white people from an individual understanding of racism - i.e. only some people are racist and those people are bad - to a structural understanding.
