I think those that say we don't register transwomen are confusing outward recognition with internal. I see transwomen and know they are trans. I don't say anything to him, or about him, in his presence but I do see a man dressed as a woman.
It's not the clothing, makeup, hairstyles that so many transwomen think makes them female. It's the gait, the shoulders, the stooping if they are tall, the feet and hands, the height, the hips and often the air of entitlement... there is so much that gives it away even for the men who think they pass. They don't.
Silence from women does not equal ignorance.
