No, Buzzer. We're talking about an immigrant who has lived in another country for 40 years now and how their process of transformation might serve as a possible analogy for trans-racialism.
First off, transracialism is being completely misused under a completely incorrect definition in this entire discussion. There is no such thing as transracialism as a close analog to transexuality. The term completely predates Bruce Jenner shining a public spotlight on transexuality, and does not have the meaning you are giving it here.
One is not black because they
feel black,
act black or
wish to live in a way emulating an image of black. They are not black by gaining citizenship to Black Nation. There are not assigned social and behavioral and cultural norms inherent to blackness that, once adopted, makes one black. There is no relationship between transracialism and transexuality.
What is the essential component of race at play there that is important to recognize?
In many cases, thousands of years of heritage or experiences which uniquely or differentially affected the experiences of one group of people against the broader pool of the human population. This can take the form of specific physical and health considerations. This can take the form of diet. This can take the form of generationally imprinted experiences which affected the group-- slavery, genocide.
There is no mathematical constant to race because race is a social construct. That is the point at which many white people have their easy out and throw up their hands and go, "Well, see? Race isn't even real. So why is anyone making any kind of fuss about it at all? It's only a problem if they IMAGINE it's a problem, and it's only real if they TREAT it like it is." That's total bullshit. Race may be socially constructed. But the resulting groupings, experiences and heritage that results from people being cordoned off and viewed as a separate race are
real.
In 100 years down the line, one could no doubt just as easily adopt your position on sexuality, and imply there is not, and never was, any reason to ever view or acknowledge any difference at all... and criticize and belittle the notion that anyone ever "identified" around a sexual orientation. But there
is a common set of concerns, and in most cases, a common set of experiences and histories which presented themselves to individuals who are gay
because they were gay. Now let's say being gay is something no one was ever capable of hiding. Then extend the period over which society categorized and treated gay people differently back for centuries, or millenia, and you start to get some kind of glimpse of what, in many cases, race is, and why its existence as a facet of identity is real, even if debunked presumptions in the past of biological and innate differences between humans by race never was.
