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)
I’m not saying the physical traits you are talking about aren’t real. I’m saying you’re using the wrong word to describe them. Biologically there is no such thing as different human races. You are talking about ethnic groups.
If you take two people from an African country they can be genetically closer to an European or Asian person than to each other.
