This part of the article really stood out as awkward placement to me. As a white guy dating a black woman, we often go to events with her friends or family where I am the only white person and it can be quite unwelcoming especially at some night clubs. This idea that if you're white you fit in anywhere has such disconnect from reality.
Relative privilege still applies here. The "only person of of my race in the room" is new for you, but ubiquitous for a huge number of POCs, especially when climbing the corporate/academic ladder.
