The Mother of a Movement is a true story of parental support and unconditional love. It tells the story of Jeanne Manford, the founder of PFLAG. When her son Morty was beaten by New York City officials for handing out pro-gay leaflets, Manford wrote a powerful letter to the New York Post to complain about how Morty was treated. In the letter she came out as the mother of a gay son. The letter was published. Morty invited his mother to march with him in the June 1972 Christopher Street Parade. While marching, she had the idea to form a group to help parents and families of LGBTQ+ people. That was the beginning of PFLAG.
