Comparing transracial identity to transgender identity strikes me as very much along the same idea as comparing the anti-vax position to modern immunology because, after all, they’re both theories and we should “teach the debate.”
The word and self-identity of LGBT people has never been sufficient. Medicine and psychology has reluctantly come to support and acceptance in the 21st century. This happened because the alternatives were proven failures that were more brutal than non-intervention. We can debate the etiology and ontology of sexual and gender identities until the cows come home. We can’t debate the practical problem that attempts to coercively change those identities kill people.
