Note that I'm talking about real, actual men and women here; not the stereotypes that folks have in their head, but the actual people they want to do editorial work.
A better example: What about guns? The gender balance when it comes to vocal, visible people who like guns is heavily skewed towards males, but people don't call out gun control advocates as causing trouble for 'men's issues', or 'trying to silence men'.
The issue here is less 'geeks hate women, and so women's articles suffer in wikipedia', and more 'geeks care less about subjects outside their bailiwick, like fashion, and so those articles suffer in wikipedia'. The question is really 'how do we loosen the reins of the geeks a little', not 'there's not enough Genital Type V amongst our editors'.
Here is an example of what can happen when people think that love of fashion is inherent to being female. It's an ad campaign using fashion imagery to attract girls to science - and you wouldn't see a parallel campaign using guns to attract boys to be a teacher, would you? Or racecars to be a nurse?
