What is the Fear for Whites to Talk About Racism?

My group experience as a community therapist and facilitator has taught me that whenever there is denial and/or defensiveness, there is also a fear and need to protect something or someone. I think that the general reaction of most whites is that when the subject of racism comes up, they will be scapegoated and blamed by BIPOC, and that the focus of discussion will be on how they have continued to perpetuate racism.
