 The sexual revolution in the 1970s introduced the differentiation between identity and sexual behavior for women. Many women took advantage of their new social freedom to try new experiences. Women who previously identified as heterosexual tried sleeping with women, though many maintained their heterosexual identity. However, with the advent of second wave feminism, lesbian as a political identity grew to describe a social philosophy among women, often overshadowing sexual desire as a defining trait. A militant feminist organization named Radicalesbians published a manifesto in 1970 entitled "The Woman-Identified Woman" that declared "A lesbian is the rage of all women condensed to the point of explosion".
