I have some issues with your generalization that women who have good sysadmin skills as you outline them don't suffer from sexism. I have them and I do still see it in my workplace. I am a geek, I have always been a geek.

When I was a manager and not a tech, yes, I saw less of it. But as a tech it is pervasive. And I'm really confused how you can equate handling Word macros with managing hundreds or thousands of servers, or petabytes of storage like I do.
