I often think there's a subset of people that have scripts to search Hacker News for 'gender' or 'sex' just so they can get involved with a "I identify as a rare breed of pineapple" and "muh gender" type of comment.

The only thing that's funny is that on a thread about lab rats reacting differently to male or female lab workers, people feel the need to start a holy war about topics as pointless as this one.
