My wife is a gamer. You will respect her and act civil or you will gtfo. That being said a sense of humor is required for any fire team. There are always people that like to tip toe on that line though and she has no problem letting them know when they are nearing the danger zone. But she doesn't invent issues. I find that some people (not just women) go into things looking for reasons to be pissed off and have a hair trigger. Be it because they didn't want to be there in the first place, feel inadequate and/or feel uncomfortable to start with. I try to make her and the rest of my team feel as comfortable as I can. And a little humor (silly but not annoying) can go a long way.
