one is an issue that people struggle with,
identity and not just as a social construct but also biological

race, yes is also social construct that bears material meaning, repercussion, expression etc
in this country, race is a stand-in for ethnicity

with this particular scenario
people are trying to make transrace a thing when its really about a woman who chose to lie
that's not a 'thing'
if it was, we would have more examples of people
coming out to define what their transrace'ism is

we dont, we are instead arguing hypotheticals.
