Naming no names or pointing fingers:
I know quite a few from the Fuel Rats. Oddly enough there were at least 3 that I didn't know were female until somebody else referred to them as "her" or "she". irc chat without images and 100+ people means unless you properly analyse each persons manner of writing it's unlikely you'll spot differences beyond: They use a spellchecker, they use slang etc.
Partly I felt that was incredibly sexist of me as it could be construed as me "assuming that everyone is a man". However, looking back I never really made any assumptions, merely never thought about it as their gender didn't affect my interactions with them. Similarly there's one or two people in there that shared they had a form of disability. Again pondered the above and figured it didn't matter. From what I've seen no matter who you are on the Fuel Rats irc you are just like any other person and treated as such which I think is an excellent thing although the whole topic can be such a minefield of not wanting to put words in anyones mouth I'll leave it here and just say whoever you are, whatever your circumstances if you can type, fly in Elite and have some patience then you will be made welcome in the Fuel Rats
As for the ratio, yes the ratio is incredibly high. iirc the male/female ratio in the world is about 50/50 but I'd not be at all shocked to learn that Elite was 95/5 or similar. Probably video games as a whole is a 80/20 split, possibly +10% either way I don't really follow. Who knows the true figures but lets say its skewed one way. On the other side there are female dominated activities with similar ratios.
Should we try to even it up? No, we can't force people to do things or set quotas or target advertisements, positive discrimination is still discrimination in my eyes.
Should we try and make anyone welcome and do everything we can to make it an equal place? Of course.
Bear in mind a lot of the above is my opinion, feel free to disagree.
I believe I've seen actual studies indicate that the actual ratio is more like 60/40, however again, the girls/woman are not going to reveal themselves, I've known enough female players through the years, to believe that the ratio could easily be up there, you simply do not hear it, because of how the gaming environment would be if they revealed they are female.
