Equal Rights for Women, or Woman's Liberation became the most significant civil rights movement after 1966. The roots of this movement can be traced back to 1963, when Betty Freidan published her book "The Feminine Mystique". That book was a best seller and gave Betty Freidan the momentum to organize NOW (The National Organization for Woman) NOW spent most of the 1970s trying to get the Equal Rights Amendment passed. That effort eventually fizzled out, in the 1980s, but most of the goals of the Equal Rights Amendment were achieved through federal legislation that prohibited discrimination against women, in the work place. Betty Freidan was at the vanguard of the Second Wave of woman's liberation. The first wave, was the struggle to give women the right to vote, but that was achieved in 1920.
Betty Freidan was concerned about economic issues and was something of a roadblock to the gay rights movement, during the 1970s. She would not allow Lesbians to speak at important NOW meetings and it wasn't until 2000 that Betty Freidan apologized for dragging her feet on gay rights.
Gay rights as a civil rights movement lagged behind the woman's liberation movement by five years. It did not make any progress until the 1970s, then the AIDS epidemic set it back by some ten years. Too many Gay Rights activists were cut down by the disease and the need to control HIV took the attention away from Gay rights in the mid to late 1980s. Once medical ways of controlling the effects of HIV and no longer made it a death sentence, could any advances be made of Gay civil rights.
