Did Dr. Spitzer regret his participation in the video?
Yes and no. He did tell a questioner by email that he regretted his participation in anything that would deny equal rights to homosexuals. However, he also continues to believe that change may be possible for a small subset of individuals and that the professions should incorporate his findings into their position statements on the subject. Thus, he is fine with what he said on the video but he regrets any use of the film in an activist manner. I reproduced a transcript of my interview with Dr. Spitzer on my blog.
