Similar to Kameny's regret at his own reaction to the shift in attitudes after the riots, Randy Wicker came to describe his embarrassment as "one of the greatest mistakes of his life". The image of gay people retaliating against police, after so many years of allowing such treatment to go unchallenged, "stirred an unexpected spirit among many homosexuals". Kay Lahusen, who photographed the marches in 1965, stated, "Up to 1969, this movement was generally called the homosexual or homophile movement... Many new activists consider the Stonewall uprising the birth of the gay liberation movement. Certainly it was the birth of gay pride on a massive scale." David Carter, in his article "What made Stonewall different", explained that even though there were several uprisings before Stonewall, the reason Stonewall was so historical was that thousands of people were involved, the riot lasted a long time (six days), it was the first to get major media coverage, and it sparked the formation of many gay rights groups.
