Feminists

but there was a significant (and vocal) subgroup which was pretty insistent about complete separation from men. Never made sense to me, so I put my energies elsewhere for a few more years.

Here is almost word for word what I remember from my freshman year in college in 1974:

"In addition to advocating withdrawal from working, personal or casual relationships with men, The Furies recommended that Lesbian Separatists relate "only (with) women who cut their ties to male privilege" and suggest that "as long as women still benefit from heterosexuality, receive its privileges and security, they will at some point have to betray their sisters, especially Lesbian sisters who do not receive those benefits.""
