I don't know if it really exists, how it works, or why it exist?

I'm just going off what the article said. From the article it seems like she went through the female calibration and they spotted an "anomaly" (aka a penis) that had to be investigated.

She then told them she was born a man. They say okay, run through the thing under the male calibration. She refuses and cries and tweets.

Does that seem like a reasonable response from her?
