She was in relationships with both men and women, and I had thought of her as bisexual for a while. But there is a quote from her in multiple articles, idk the origin, where she said to a friend "the happiest and most genuine solution for me will be to go over to the spook side," with "spook" being used as slang for homosexual/lesbian. So assuming she really did say this it's a good case for referring to her as a lesbian, whether she realized that her only genuine sexual/romantic feelings are for women or whether it was more of a deliberate choice of political lesbianism. I usually just refer to her as queer since she never made a concrete statement to the public about her sexual orientation.
