The curators are defending their public display of separatism by using the same lame excuse that white supremacists have done for centuries, ie basically "oh, we just feel more comfortable with our own kind." Where did that go? Moreover, this was staged public negativity. It's irritating they are veiling it as something creative and lofty—even hiding their intention to the public in order to trick them (which comes across as more cowardly than clever). They could be honest about the hostility of their exercise and put up a sign saying "whites invited but not allowed." White people are taken to the mat every day for their lack of compassion, and tricking them and abusing them for being white will not lead to any new compassion, or any new territory at all. If the curators sincerely wanted to enjoy a space with people of color, they could have accomplished that without the mean little tactic. I'm also disappointed the reviewer found it refreshing. I think she took the easy way out.
