The author says they are interested in the humanities and like to see articles focus on structural barriers faced by women in the workplace. I doubt however they want to see article discussing the merits of the topic, i.e. if women does face barriers in the work place. The result is that anyone who does not share the same perspective is not welcome in the discussion and the environment from that confrontation produce the opposite of thoughtful and substantive discussion.
Political discussion does not need to end like that and many topics which does not have the above property do pop up in HN.
