This expresses in much better words some of what I wrote in my submission on The Definitions Of Woman And Man Bill — Open letter to Aotearoa: Definitions of Woman and Man Bill · QueerSpace:
This puts trans people at real risk while producing the very outcome its supporters say they fear. It doesn't add any real safety but creates suspicion.
Think about who gets stopped at a bathroom door under a law that invites strangers to judge who looks female enough. Not only trans women — but the tall woman, the broad-shouldered woman, the woman with short hair. Overseas, cis women have been challenged and humiliated at bathroom doors for exactly this. This bill would give that suspicion the backing of New Zealand law.
