I just wish there were more women who were actual open-source programmers rather than journalists, executives or advocates. People like Margo Seltzer (BerkeleyDB) or Lynne Jolitz (386BSD).
Even if you have, that's problematic on your part. Just because people look differently doesn't mean they won't be welcoming towards you, that's tribalism at it's finest and needs to stop.
The ones that do feel intimidated/uneasy about it need to work on their own perception of other people and not the other way around. You don't change the mindset of a group because there isn't any, it only exists on paper in your gender studies textbooks. Humans are individuals and everyone has their own mindset regardless of genitalia, skin color, age etc. Thinking otherwise is both disrespectful and racist/sexist/agist.
Like? I'd really like to know the reasons. Also, who is "we"? Biological women? Also please explain, as I initially asked, why it matters what gender you are. (Or race, hair or eye color you have, height or whatever attributes you think is "invisible" to others and hence underrepresented)
From personal experience I know a women-only domain does not keep men from joining it. I've seen it the other way around with friends as well, unless you project something into that and start to think it would be a "problem" or discourage someone or something else. Would you join an office where everyone is a redhead but you aren't? Sure you would. I mean, why not? What would discourage you? So how is it different for a man to join an office for example with only women? Or just replace the attributes which whatever you think fits. If you care about other people's gender, race, hair color, height or number or functioning body parts (read as: "handicapped") much ... well, then there will always be an underrepresentation of some sort.
If the distribution of gender discourages you from joining a community or domain maybe you should stop putting people and yourself into categories of body attributes. To me it's the same pair of shoes as saying "too many/few black people". Ok, so they are "different" from other people in a way that would discourage someone? Interesting thought in 2019 for a pre 20th century concept.
