Just shows how these issues are compartmentalize and used when advantageous, but rarely taken seriously. If she really has a problem with the definition of a women, she couldn't make this statement. If she is committed to women in visiable roles she would be able to identify what a women is.
If she doesnt believe that sex matters and believes a self identified gender identity is key to equality for women, she would have to ask each individual their self defined gender indenity before making such a comment.
