A Christian group devoted to so-called gay “conversion” has closed its doors and apologized to the LGBT community. Exodus International had billed itself as the oldest Christian ministry devoted to the practice of trying to shame gay people into changing their sexual orientation. In an open letter to LGBT people who underwent its practices, Exodus International president Alan Chambers said the group was part of a “system of ignorance,” saying: “I am sorry for the pain and hurt that many of you have experienced. I am sorry some of you spent years working through the shame and guilt when your attractions didn’t change. I am sorry we promoted sexual orientation change efforts and reparative theories about sexual orientation that stigmatized parents.” California last year became the first state in the nation banning so-called “conversion” therapy aimed at minors.
