trans women are women prove me wrong

I'm not going to argue that trans women aren't women, because that's not the debate we're having. You've actually shifted the entire frame to avoid defending the original question about selfishness and childbearing. Smart dodge, but transparent. If you want to defend the claim that choosing not to have children is selfish, make that case. Otherwise, you're conceding the point by changing the subject. So which is it, we discussing reproductive choices or are you retreating to safer ground?
