Influence has a way of perpetuating itself, especially when its protected by nerdy little enclaves. So you are saying that because women (or mexicans or furries) did not contribute in the past, they now deserve to be excluded in the future?
No, I would hope to see more work from (and proportionately more influence for) women on Wikipedia. But the article presents what seems to be the result of past inaction, back when Wikipedia was a meritocracy, as a Women's Rights issue. Yes, there is a gender bias on Wikipedia now, and even chauvinistic behavior. We should get rid of both, if possible, which may be difficult as such an environment is not inviting to women.
