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)
Race is an extremely unscientific way to catagorize human beings, and it’s no wonder these people claim to be trans racial instead of trans ethnic. The more scientific, cultural, and hereditary definition of ethnicity means they’d have no real arguement to claim an ethnicity they weren’t raised in and have no heritage from but the loose political definition of race gives them lots of wiggle room.
Tldr: tell them race isnt real and ethnicity is based on the culture you were raised in and the heritage of your ancestors. You can’t force your ancestors to be a different ethnicity and you can transition a childhood upbringing, just an identity.
Regardless of culture/ethnicity: two asians have a baby, you get an asian baby.
Regardless of culture/ethnicity: two slavs have a baby, you get a salvic baby.
Race is most certainly real.
Slavs are not a race, but ethnic group.
Two Koreans have a baby, the baby is Korean. Indian and Japanese have a baby, and you got something wildly different from either.
Sure, a Black person looks different from White, but within both there is so much variation that it doesn’t make much sense to group them so roughly.
