Sorry, but I think you misread that. She isn't saying that about her work. She's saying that about the challenge of being the only woman around, and not only of putting up with sexism but in this case the challenge of worrying about sexism. She didn't say that her manager should be the one she can talk to. In fact, this is a pretty textbook case of why it's helpful to have groups for women in programming, so you can reality check each other with things like 'nah, that guy is actually a giant asshole to everyone, not just you/women'.
