I disagree. It shows that far more gender-neutral or boy names become significantly more popular as girl names, compared to the other way around. That's pretty interesting.

This conforms to the idea that a boy with a girl's name (or other girlish attribute) is bad, whereas a girl with a boy's name (or other boyish attribute) is not as bad, or is even good.
