The commenter does have a point. Considering blacks couldn't really vote until the 60's, and women make up the majority of the electorate, it is a greater statistical injustice for women not to have reached the presidency. Especially because there are many more qualified women (how many female governors and senators vs. how many minority governors and senators?).
Women couldn't vote nationwide until 1920, though many jurisdictions allowed them to vote before that. Blacks living in the North could vote before the 60s, though very, very few were elected to office. Also, until recently it was almost impossible for black politicians to go statewide.
The "problem," of course, is that young women don't necessarily overwhelmingly identify with their gender and it's not going to change anytime soon. And Hillary wasn't very feminine by societal standards.
That was one of the main problems Hillary ran up against during the primary, and to a large degree it was due to the success of the women's movement. Younger women had grown up equal to their male peers in most respects, didn't feel oppressed, and thus didn't see the need to elect a woman to office.
