I don't think anyone was suggesting excluding the benefited group (nor, really, is there any evidence young people is an area we lack contribution from :P). At no point was saying "women can't get involved in this process" discussed - that'd be counterproductive. Your idea of having dedicated female-friendly areas seems contradictory. 1) it segregates the community, 2) if the main community isn't female-friendly, we should be tackling that, not trying to shield people from the issues and 3) if the main community isn't female friendly, bringing potential female editors into a "female-friendly" niche environment and then dropping them in the main community seems rather akin to the story of itsy-bitsy spider and his waterspout.
