Within two years of the Stonewall riots there were gay rights groups in every major American city, as well as Canada, Australia, and Western Europe. People who joined activist organizations after the riots had very little in common other than their same-sex attraction. Many who arrived at GLF or GAA meetings were taken aback by the number of gay people in one place. Race, class, ideology, and gender became frequent obstacles in the years after the riots. This was illustrated during the 1973 Stonewall rally when, moments after Barbara Gittings exuberantly praised the diversity of the crowd, feminist activist Jean O'Leary protested what she perceived as the mocking of women by cross-dressers and drag queens in attendance. During a speech by O'Leary, in which she claimed that drag queens made fun of women for entertainment value and profit, Sylvia Rivera and Lee Brewster jumped on the stage and shouted "You go to bars because of what drag queens did for you, and "these bitches" tell us to quit being ourselves!" Both the drag queens and lesbian feminists in attendance left in disgust.
