I think Mary Wollstonecraft was queer. Bisexual to be exact.
I've been reading about her and there's all these references to her "friends" and "companions" who are all women. She does later in life marry a guy, get divorced, and marry another guy, but most of her life is spent with women "companions" Including this one chick that she moves out of her father's house to be with. She's kinda a badass lady.

Then again, maybe I just want her to be queer because I have a crush on her and the things she wrote.
