If you are a girl gamer, you can share your experiences with others not treating you the way they should.
As for me, I treat them as fairly as a can, but sometimes I would put a girl on my list of friends online in front of others (I know, that's sad). I don't talk to them as much as I can, it's just actually talking to a girl seems new to me all the time. Definitively not like high school, I never talk to girls =(Forever alone)=.
Others I've met online however, make sexist comments like: "Get back in the kitchen and make me a sandwich!". Sometimes it would be cheesy chat up lines like: "If I could rearrange the alphabet, I'd put U and I together." which I have heard at least 20 times. Comments that are usually from prepubescent kids.
To see how it would be like being commented on by sexist bastards online, on Halo: Reach I made my character female with white and pink armour (make fun of me if you want). I played a couple of matches in multiplayer and then joined some recent players in their open custom games.
I eventually joined a custom game with only 2 players, some guy without a mic and a little kid who probably sleeps in a racecar bed. When they finally saw my character as a woman, the first thing the little kid said to me was "Hay, are you a girl?" I chose to not plug my mic in just encase he asks me to speak, then I sent him a text message saying "Yes, I am a girl -_-". After a couple of minutes me killing them over and over again, the little kid started saying things like "Go to the kitchen where you belong", etc.
Once I left their game the other person without a mic sent me a text message which said: "I'm gonna rape you some day" and another simply only having the word "*****".
I never contacted them after that, until EXACTLY a month later, (with messages only appearing in your inbox a maximum of 30 days) the little kid, I had met 1 month earlier, sent me a friend request.
I was in a "What the f*ck?" moment, me finding out someone who made offensive comments to a (pretend) girl would keep a message from one for a whole month and wanted to be friends. I didn't know how to react to that, so I ignored the request.
It's really these kinds of people that don't deserve to talk online. Maybe this is like you, maybe not. If you are like this, please don't abuse the fact that you can be offensive online and not have any consequences. Be honest with yourself.
Anyway, back to the question... Do you treat girl gamers the same?
