Can someone be transracial?

'Transracial' used to refer to transracial adoption

Question: Can someone be transracial?
Position1 of 2›: Being transracial is a legitimate identity
Argument‹3 of 3: 'Transracial' used to refer to transracial adoption

Before Rachel Dolezal used to term transracial to mean transitioning from one race to another, the word was most commonly associated with transracial adoption.

The argument

The word "transracialism" changed definitions after the scandal with Rachel Dolezal's new black identity. In reality, the term is associated with adopting children and raising them in a different country and society, so they learn those cultural customs instead of the ones they were born into. This use of the term transracial is valid and reasonable. Transracially adopted children are never accused of choosing to change to a different race and ethnicity. Adopting from other countries decreases the number of children in orphanages and provides them with a better life. Identifying as transracial is valid, but not when it is defined as transitioning from one race to another.

Premises

[P1]Before the Rachel Dolezal scandal, 'transracial' referred to adopting children across countries and raising them within a different culture, a sense in which no one is accused of choosing to change race. [P2] This adoption meaning is valid and beneficial—reducing the number of children in orphanages—whereas the newer sense of transitioning from one race to another is not. [C] The transracial-adoption use of the term is a legitimate identity, unlike the claim of changing one's race.

Counter-arguments

Transracial adoption has potential negative side effects for the child being adopted. Often, they feel like the outsider of their families due to their physical appearance and commonly being mistaken as someone else. This consequently makes the person feel lonely and isolated. Yet, they cannot completely integrate into their racial group because of being raised in a different culture. Transracial adoptees feel like they cannot identify with the race they were born to or raised in, which can cause an identity crisis and mental health issues.

Rejecting the premises

[Rejecting P1] The history is the wrong way round for the premise: "transracial" as a description of adoption and "transracial" as a claim about identity are separate coinages rather than one term whose meaning changed, so establishing the older usage does not show the newer one is a corruption of it. [Rejecting P2] More seriously, the conclusion does not support the position it sits under: the argument explicitly denies that transitioning between races is legitimate and affirms only that adoptive placement across races is — which is a claim about a child's upbringing, not about anyone's identity, and so leaves the question this debate asks entirely unaddressed.
