No. I would not change my race. Prosaically speaking, black people have to adapt to live in a world dominated by whites. Just changing my skin tone and facial features wouldn’t even come close to giving me all the little soft skills it takes to live here while black. If you were to somehow magically transmit those skills to me, maybe I could consider it, but would still default to ‘no’ unless I could discern some kind of benefit.
Louis C.K. has an excellent bit about the topic:
Race in America, is, sadly, a component of one’s identity. I wish it didn’t have to be this way but it is. You take any hardship, and some of people that lived through that hardship end up turning it into a part of who they are. Some deaf people, some blind people, have expressed that they would not want to regain their lost sense if they could have it restored to them. It’s that painful to lose a part of yourself. The brain, when confronted with a sense of a lack of identity, can force the person to do awful things to themselves in order to regain it. Check out Body Integrity Identity Disorder.
I find this unfortunate but I’ve made my peace with it. As Popeye would say, I yam what I yam, and that’s all that I yam. I am white, and that’s as much a part of who I am as anything else.
