For an American of African descent, the notion of traveling to the past is a painful one. In no matter which time period a person like me might arrive, if I’m in Europe or a European colony, I might very likely be raped, enslaved, lynched, or all of the above. I’ve asked African American friends about which past time period they’d most like to visit, and they always agree with me that the present is the best. Brandi Brown, a young African American stand-up comedian who formerly worked in advertising, once joked that when she was asked, “Don’t you wish you could go back and work in the time of Mad Men?, her response was: “I would not like that at all! I’m a huge fan of my current rights.” The very idea of time travel, for African Americans, heightens our anxiety about the history of anti-black white supremacy in the world.
