Someone here posted about how she thought maybe she is exempt from some forms of sexism in the office because she is a lesbian. I can't for the life of me remember who it was, what it was called, or much of what it said (and I can't find it either!), and I can't speak from any level of experience, but I just wanted to post this Slate article about it.
[ETA: this was originally titled "lesbian privilege" and I definitely don't want to give the impression I think that lesbians exist in a place of privilege in general - this was just a follow up to another poster's notion that she was escaping some forms of sexism. Obviously, there are plenty of ways that her same experiences would affect other lesbians negatively]
Full disclosure: I hate read Slate and hate everything on there 99% of the time. I don't specifically hate this article, but don't feel that I have much to add. I'm cis, feminine, and have always worked in women-majority companies run by women (so while there is sexism, it's different).
