Looking at the responses here (so far) - I'd say the problem (with this topic on HN) is too many people with both heavy axes to grind, and instincts to treat "men" and "women" as simplistic monoliths.

You could get similarly poor discussion on other topics if people assumed that all c code is hopelessly insecure, and that all PHP code was written by a clueless noob in 1998, and that WordPress had no legit use cases, and ...

The problem is that "men's problems" not only is not where the money is, it often brings up discussions and ideas that actively go against the prevailing politics. Any person has a short-term gain to be had in disassociating themselves with this topic.
