Edit for context:
My view is transracial isn’t valid and this person is trying to dogwhistle. I’ve already blocked this person, and now they’re going after my friend saying my friend is transphobic because they disagreed with them about transracial being a thing (they’re purposefully leaving the context out so my friend looks transphobic when what my friend really said was transgender is valid but transracial isn’t)
This is the shit I was responding too. And rhetoric like that is painfully contrary to even elementary biology. If the best response to OP’s question is a demonstrably false statement like ‘race isn’t real’, well, that’s a very sad state of affairs.
Just as I wouldn’t generally find it necessary to group people by eye color, the fact remains eye color is real. Same for other genetically determined things like race.
Where do you put children of parents of different races, then?
And the offspring of such children?
Many if not most people on Earth have a combined descent.
