What a utterly stupid thing to even have on the card. Just do away with gender if you want to put a mystery box as a option.

It does me no good as a first responder and as a healthcare worker.

ID is specifically designed to help identify who and what a person is. This flies in the face of that purpose and negates its ability to be useful. People really are just this stupid.

Edit: women have different organs, hormones, vital sign normals, different lab values, pregnancy in general and the various reproductive conditions that can be missed and be deadly. I can go on and on as to why it's important for officials to know the xx or xy status of a person strictly for medical and legal reasons.
