Here's post for anyone confused as to why transracialism and transgenderism can't be compared:
"Race is a purely social/cultural construct. A white person growing up around black people in a black culture will likely behave the same way those around them do (barring outside influences like media telling them they shouldn't). Same goes for black people growing up around white people in a white culture. Race is literally just the color of your skin, it is not a biological construct, just a social one.
Gender, on the other hand, is both social AND neuropsychological, meaning that behaviorally it is influenced both by your environment as well as your hormones, your biology, and other factors. For this reason, across all cultures, women and men share a few characteristics that distinguish them from one another outside of biological things like genitals. The same could not be said for race.
In short, there is a biological reason why someone might identify as a woman in spite of having male genitalia. A woman who has male genitalia cannot live as a woman with expressing as one, while a white person who identifies with black culture can consume the media and integrate with the social group without identifying as black themselves. It's like the distinction between someone who is transgender and someone who is a tomboy. Girls who are tomboys are still girls, they just enjoy expressing some masculine traits. They identify as women, just with more masculine expression than most women. Transgender women, however, are women in identity, which differs from expression. There is no such thing as "black on the inside", because black peoples' brains, white peoples' brains, asian peoples' brains, are all the same until they are altered by culture and environment. However, mens' brains and womens' brains have some distinct differences that begin in utero, with the production of hormones, either androgens or estrogens, but extend to some traits independent of those indicators. In fact, scans of transgender peoples' brains show more similarities to the gender with which they identify than to the one with which they were assigned at birth.
An interesting way to look at this is to look at people who are intersex. While there are people who are queer, third gender, bigender, gender fluid, etc, most people who are intersex (born with ambiguous genitalia, or some sex-related disorder like androgen insensitivity [previously known as hermaphrodites]) identify as one gender or the other. However, when someone is mixed race, they usually identify with either both races, their dominant race, or the race that is most apparent in their appearance, or the race with which they are most familiar. While gender is not binary, most people reside in one side or the other (man or woman) while race is a complete spectrum. Gender is biology that is informed by environment, while race is literally no different than eye or hair color (biologically speaking); it's only when society gets involved that issues of race become anything."
about at first
If you can't tell that a person of African descent by looking at them then they aren't black. It doesn't anymore simple than that. You really are a gotdamn idiot.
