Where to start with this?
If the answer to this is 'No, because it's a woman' Then your issue is not actually about women's concern for safety, its that you refuse to see trans women as they identify.
It's not a refusal to "see" someone as they identify, I simply can't convince my eyes to lie. Transwomen are men and my eyes tell me so.
Men, however they identify, pose more of a risk to women than other women do.
I have no idea how many lesbians I've shared a changing room with because I've never been made to feel uncomfortable by another woman. It's the sex, not sexual orientation, of others in the changing room which bothers me. You are clearly homophobic which is why you think you have made a compelling argument.
Many men, in public spaces, have behaved in ways which made me feel uncomfortable so I'd rather they weren't in the same changing room.
