Alan Chambers is a guy in process.
In January, 2012, Chambers made news by acknowledging the rarity of sexual reorientation (“99.9% of them haven’t experienced change”). Since then, he and Exodus International have removed themselves from the reparative therapy world entirely. Today, on the eve of what promises to be a riveting television appearance on the Oprah Network, Chambers has issued a written apology to the LGBTQ community.
Please do go read the whole article, but let me pull out an extraordinary paragraph:

Please know that I am deeply sorry. I am sorry for the pain and hurt many of you have experienced. I am sorry that some of you spent years working through the shame and guilt you felt when your attractions didn’t change. I am sorry we promoted sexual orientation change efforts and reparative theories about sexual orientation that stigmatized parents. I am sorry that there were times I didn’t stand up to people publicly “on my side” who called you names like sodomite—or worse. I am sorry that I, knowing some of you so well, failed to share publicly that the gay and lesbian people I know were every bit as capable of being amazing parents as the straight people that I know. I am sorry that when I celebrated a person coming to Christ and surrendering their sexuality to Him that I callously celebrated the end of relationships that broke your heart. I am sorry that I have communicated that you and your families are less than me and mine. 

Here Alan has really turned the corner on his earlier support for Love Won Out and NARTH.
