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)
The best way to respond is to disregard them, block and move on. Transracial is an actual thing, but it refers to people of one race adopted by another. Transracial ala Dolezal is just a troll to attack trans people, no different from attack helicopters.
It’s not even a race, it’s usually a community with a different culture, so the entire term is invalid. And humans are one species with no races, despite this we keep the divisions that the less educated from history created.
I think a better word for it would be “Transcultural” or “Transethnithicy” ?
But I’ve never heard of that specifically, closest people I know of are people with parents from other cultures who grew up in a different culture than one or both parents, call themselves “multicultural” or as having “multiethnicity”…
