A quote from Eve Sedgwick
From Eve Kosofsky Sedgwick's Between Men: English Literature and Male Homosocial Desire:
"Our own society is brutally homophobic; and homophobia directed against both males and females is not arbitrary or gratuitous, but tightly knit into the texture of family, gender, age, class, and race relations. Our society could not cease to be homophobic and have its economic and political structures remain unchanged.
Nevertheless, it has yet to be demonstrated that, because most patriarchies structurally include homophobia, therefore patriarchy structurally requires homophobia."
Keep in mind that this was published in 1985.
