and recognition The riots spawned from a bar raid became a literal example of gay men and lesbians fighting back and a symbolic call to arms for many people. Historian David Carter remarks in his book about the Stonewall riots that the bar itself was a complex business that represented a community center, an opportunity for the Mafia to blackmail its own customers, a home, and a place of "exploitation and degradation". The true legacy of the Stonewall riots, Carter insists, is the "ongoing struggle for lesbian, gay, bisexual, and transgender equality".

But that night, for the first time, the usual acquiescence turned into violent resistance... From that night the lives of millions of gay men and lesbians and the attitude toward them of the larger culture in which they lived, began to change rapidly. People began to appear in public as homosexuals, demanding respect. Historian Lillian Faderman calls the riots the "shot heard round the world", explaining, "The Stonewall Rebellion was crucial because it sounded the rally for that movement. It became an emblem of gay and lesbian power. By calling on the dramatic tactic of violent protest that was being used by other oppressed groups, the events
