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)
Uhh while gender is a social construct that’s existed in countless forms though out all of history.
Sex and transsexual are VERY much a biological thing.
You can’t just say trans isn’t biological. Transgendered isn’t, but gender isn’t biology.
Sex IS biology and transsexual IS biological.
You need to be specific if you want to get into actually defined scientific terminology.
