You're thinking of this from an old Jack Thompson/mom view instead of seeing how skewed the industry is toward men. Games are made by men for men, so women are represented poorly, so then women can't relate to gaming. It's an opportunity for the industry to grow into becoming ubiquitous entertainment for everyone just like any other form of entertainment.
That doesn't really address the issue though.
The general ideological view is the same, that video games create some negative real world behavior and that things should change according 'their' direction in order to address that.
If that claim cannot be backed up, and it hasn't, there is no reason to address their concerns.
It is from my perspective the same ideological argument made by Jack Thompson/Religious Activists of the 90s, one which many people would openly disagree.
To your point, the lack of interested women in video games, is not inherently a bad thing, as horrific as that sounds.
There are any number of interests and hobbies or subsections of interests and hobbies in the world which have significant disparity in interest between sexes.
Men tend to like watching professional and collegiate sports more often than women.
Women clearly tend to have more interest in fashion and clothing than men on average.
I've yet to see anybody make any reasonable argument that this is a bad thing.
If the minority sex wishes to participate they're perfectly welcome to.
If they want representation they receive it by participating in the medium, creating their own content, or contributing to existing projects, not by calling the majority sex prejudiced.
If men play more video games, it's entirely reasonable that more video games be marketed to their tastes.
It's not as though there's a complete lack of female representation or that women aren't allowed to participate in male oriented content.
In fact, a significant part of video games, is escaping the constrains of your real-world identity such that it wouldn't really matter what sex you were.
