Then you should hold women to higher standards without excluding them completely.
So, historically this is somewhat similar to what happened--if a woman managed to get some sort of advocate / ally, she had limited access to the scientific / mathematical world as a scientist or mathematician. (Getting access to that world by hosting a salon was the typical path women would take, but that would put them much more in a support role.) But it had clear inefficiencies--Emmy Noether was unable to get a professorship in Germany, for example, and then even in America taught at a women's college, despite being a clearly first-rate mathematician.
One partial solution is to have some procedure by which Noether is declared an honorary man, and then gets full access. It is interesting to try to figure out how much of the distance this would cross between how things actually were and the ideal case, for varying strength of filtering. One can also imagine this smoothly progressing from a minor, reversible change to the ideal case, but because of that one can also see the slippery slope arguments that would have defeated it (since probably someone thought of this at the time).
(Whenever this subject comes up and we talk about people who managed to get around restrictions, it's probably also important to talk about people who couldn't get around those restrictions, not because of their ability but because of the economics or power dynamics involved. Noether had trouble getting paid for doing math, but it's cheap to do math; Jennie Cobb could find jobs flying planes but it's not cheap to go to space.)
A few notes about the site mechanics
A few notes about the community
If English is not your first language, don't let that make you afraid to post or comment. You can get English help on Discussion- or Main-level posts by sending a PM to one of the following users (use the "send message" link on the upper right of their user page). Either put the text of the post in the PM, or just say that you'd like English help and you'll get a response with an email address.

A note for theists: you will find the Less Wrong community to be predominantly atheist, though not completely so, and most of us are genuinely respectful of religious people who keep the usual community norms. It's worth saying that we might think religion is off-topic in some places where you think it's on-topic, so be thoughtful about where and how you start explicitly talking about it; some of us are happy to talk about religion, some of us aren't interested. Bear in mind that many of us really, truly have given full consideration to theistic claims and found them to be false, so starting with the most common arguments is pretty likely just to annoy people. Anyhow, it's absolutely OK to mention that you're religious in your welcome post and to invite a discussion there.
A list of some posts that are pretty awesome
I recommend the major sequences to everybody, but I realize how daunting they look at first. So for purposes of immediate gratification, the following posts are particularly interesting/illuminating/provocative and don't require any previous reading:
More suggestions are welcome! Or just check out the top-rated posts from the history of Less Wrong. Most posts at +50 or more are well worth your time.
Welcome to Less Wrong, and we look forward to hearing from you throughout the site!
Once a post gets over 500 comments, the site stops showing them all by default. If this post has 500 comments and you have 20 karma, please do start the next welcome post; a new post is a good perennial way to encourage newcomers and lurkers to introduce themselves. (Step-by-step, foolproof instructions here; takes <180seconds.)
If there's anything I should add or update on this post (especially broken links), please send me a private message—I may not notice a comment on the post.
Finally, a big thank you to everyone that helped write this post via its predecessors!
