Primarily, racism is something we are inside rather than something inside us. Not only does racism as an oppression have the element of prejudice but it also has social power. And social power means that there are racist behaviours that are either condoned, encouraged or required by the culture. There's no such thing as reverse racism because there's no such thing as a simple reversal of the power relationships between whites and blacks. Victor distinguishes between racism and xenophobia.
Xenophobia is an irrational fear or hatred of one defined as the other or as a stranger.
Any group of people in any location in society can be xenophobic. But in the current context only white people can be racist because the racial prejudice of xenophobia of white people will reinforce white dominance and the racial prejudice of xenophobia of people of colour will reinforce white dominance and that's because racism is a system of institutions and material institutions, social power, economic and political power, and the capacity to inflict violence. For white people Victor addressed himself to white people in the workshop I attended. If you fear you are racist, fear not. I'm not sure that not being part of the problem is an option for white people at all.
