It is unfortunate that Rachel Dolezal is the current poster child for “transrace” because in her situation she was benefitting materially from claiming an identity as black person, which makes the entire possibility of claiming identity as another race look creepy and suspect. And actually I think we, as a society, should embrace it. I certainly believe there is no intrinsic set of race characteristics at the personality-and-behavior level. (As opposed to things like a tendency to have sickle cell trait, etc, I mean). So race is “all in the head”. And yet it certainly exists socially. We have notions about what it means to be “of” this or that race, and however much some of us would prefer that those notions all go away and vanish from everyone’s heads as harmful and restrictive, they are still persistent and pervasive.
So an individual person simply feels they aren’t at all “at home” with people of their own racial background. They gravitate towards a different cluster of people (presumably people who don’t hold unduly rigid notions of race themselves, but also presumably a cluster of people whose own racial makeup consists mostly of folks of a different racial background than our hypothetical individual). And they feel that this is where they belong, among these folks.
Yes, you could say “you should instead seek to be accepted for how and who you are AS a member of the race to which you were born”. But, as with gender, that’s going to translate as “you should set aside any desire to fit in with a community you feel you could fit in with, and instead devote your life to a goal of social change that won’t be attained in your own lifetime”.
I’ve known several people born of black families who rejected the notion of being black. Most of them didn’t do an inverse Rachel Dolezal and go around telling folks they were white, but one hung out in the East Village countercultural scene in the 60s and traveled with hard rock bands for years, accepted there as “one of us”, fitting in with a social cohort that was otherwise composed nearly exclusively of white folks; and one pursued an academic career as a cerebral university professor with zero discernable behavioral nuances or speech patterns typically associated with black people, while promoting a social theory that said all American social inequality affecting black people today is entirely about class and income and not about race itself —i.e., he “doesn’t believe in race” (and was remarked upon by grad students with varying degrees of approval and skeptical disapproval as someone who “presented white”).
I’ve known more than a few whiteborn people who rejected any sense of whiteness as their own identity, too. Some found white culture dead and lacking intensity and real feeling, or full of poisonous values and priorities they could not relate to; some were just immersed early in some other culture (hispanic or black) that they initially fit into effortlessly when young and weren’t willing to give that up.
So, if it were a specific individual who seemed to have formed most of that identity from a core experience of negative views of people of their own race? Yeah, it could mean we’re seeing an expression of self-hatred and denial there. I recall a black woman who wanted to be a part of the KKK awhile back. And stories that Hitler was Jewish or part Jewish and knew it. But I think it’s a mistake to assume that everyone who pushes away from an identity because they have come to hold very negative views of that identity (or of the people of whom that identity is composed) is expressing self-hatred. That viewpoint has an essentialism in it, the notion that who the person “really is” is the category they have rejected as their identity.
