Given that endorsement is a mechanism which can only reduce the quantity of discussion on HN, it is difficult to imagine that it is designed to open up a discussion to more viewpoints.
I think your choice of "female work experience in technology fields" is interesting because it is one of the few legitimate topics where there isn't widespread agreement on basic foundations around the topic.
Others topics that fall into that category include "The Economics of Bitcoin", "Is Google Evil", "Startup X was bought by large company Y".
There's also a wide range of political & economic topics which are always controversial, but sometimes I question their legitimacy as a topic for HN.
I wonder if these controversial topics should have special handling so far as endorsement (and maybe even voting) on comments goes?
