I've seen many people who are white get irritated by the idea of being called white by POC . They quickly refer to being Irish, Italian, German, French... Even inside of being white, white people feel the need to distinguish themselves further.
I see how this leads to white people being afraid to talk about race, because they already are trying to view themselves as unique. White people are always trying to make themselves the most special and this is threatened by the idea of uniqueness. When POC are unique you see white envy, cultural appropriation, white erasure and mocking. Such as the woman holding the Ted talk some about when the white people in their class used their white privilege to silence POC voices. It was their privilege that promoted them to be selfish enough to put their comfort level over the class. It what their privilege to shut out what they were hearing. I see white privilege abused constantly and have only a handful of examples that have showed how to use it positively.
When we can address race, implicit bias, acknowledge white privilege, and listen rather than speak... We will go much further as a diverse community.
