House rules go gender neutralFollow @freedom2marry
They went gender neutral, which is great. It recognizes the fact that many people in Congress are women and moves away from the idea that men are the more appropriate/normal/default sex of Congresscritters or people in general.
So apparently being aware of the words that are coming from one's mouth is not just for humorless feminists or dirty fucking hippies anymore.
The entire list of gender neutral changes to the House rules (links to pdf, gender changes start on page 9) is an interesting read. It doesn't take much to make language gender neutral, and it doesn't all have to be "he or she" or "his or her" if you use a little creativity.
