While I'd agree that the root cause is unfair treatment, "ladies-specific events" only server to further divide groups. I like the parent's use of "organic" - let's keep the doors open to everyone, and let the system reach equilibrium on its own.
I'd like to see your evidence that women-specific events only serve to further divide groups. The participants I've talked to see it as an opportunity to learn new skills in a safe environment. Skills that they then go out and apply at regular companies. It's not like they then go on to work at women-only companies and then found women-only startups themselves, after all.
And women-specific events reinforce a divided image by presenting the events as specific to a group. It highlights a division between groups, and not based on a functional difference relevant to the field. What's different from a women-specific coding meetup and a meetup open to all? I can see sexual harassment / feeling out of place as something that may happen. And that sucks. But retreating to exclusive events (in name and branding at least) is not the solution.
You're certainly entitled to your opinion that somebody else's solution to a problem you don't have is wrong. But unless you're planning on doing something better, I'm not sure why you think your opinion is relevant. As with any open-source project, "patches welcome" is the order of the day.
