The LGBTQ community was tired of the lack of job opportunities, the loss of employment if they were "outted," and the continual police harassment. Bars in most states would lose their liquor license if they served homosexuals. The very act of homosexual love would land a man or a woman in jail. With Stonewall, the LGBTQ community organized to demand their rights. But it had taken a lot of preparation for the struggle that continues today.
