Including a wider range of people from different points of view is certainly a nice goal, but this statement is off the deep end:
Non-profit groups, academics, and volunteers have led to efforts to correct Wikipedia’s systemic gender imbalances. Without solving it, the site will never near its goal of becoming the web’s independent, neutral arbiter of knowledge. But the going is slow.
So the only way to be an independent “arbiter of knowledge” is to hire more girls? So knowledge is based on gender?
I do not think you understand just how stupid that claim is. So knowledge is different between women and Men? How about transgender and gender neutral people? Is their capacity for knowledge different as well?
You seem to be confusing perspective and knowledge. Knowledge is knowledge, you either know certain things or you do not, how you apply that knowledge or now you perceive that knowledge can change.
