I think she should have just stuck with the confusion due to Luke’s abilities. Crying sexism seems like she’s trying to compensate due to not having an argument.
Crying sexism because it is a female name is silly, crying sexism because of the way the female name is used is not silly.
I agree though most male Mary Sues are just called overpowered so there’s not a huge difference.
