In the early 1970s, she became a founding member of The Furies Collective, a separatist lesbian feminist collective in Washington, DC that held that heterosexuality was the root of all oppression. The women wanted to create a communal living situation for radical feminists. The group purchased two houses, where they lived together and used consciousness raising techniques to talk about things like homophobia, feminism, and child rearing. They believed that being a lesbian was a political act, not just a personal one. Brown was exiled from The Furies after a few months and the group dismantled in 1972, a year after its inception.
