> Furthermore pretty much everybody in every non-western country is a TERF.

Many non-western nations traditionally had third gender (Hijras in India, Kathoey in Thailand, many Native American Two-Spirit Identities). When these places were colonized these identities were used as a justification, and generally punished harshly. The argument that "only people in western nations tolerate this", is bad-faith, and doesn't recognize that anti-trans hostility in a lot of the non-western world was largely created by the colonial overlords this argument is meant to rebuke.
