I agree with the title, as it's not optimal for role models to be primarily women who have power, success and happiness because they were born into it by luck.

However:

"Mulan is a bold Chinese warrior, respected and followed by her people…all of whom think she is a man, because she has deceived them by cutting her hair. The point here appears to be that to become a good leader, a woman should look and act like a man."

This person has severely misunderstood the point of Mulan.
