Dr. Dobson is both a medical and a psychological expert, I believe.
That is pretty silly on the face of it. I don't know if gays can be turned into heterosexuals, but for every Dobson who says he can do it, I am sure there are 10 other medical and psychological experts who say you can't.
You would think though that somebody who says they are cured, and are making a living off of that fact, can avoid going to gay bars though. Alcohol is the perfect analogy. Many alcoholics I know say they are fine, just as long as they avoid alcohol. If they have one drink though, it's over.
If this guy really thinks one can cure homosexuality, he could have worked harder. Not all gays even go to gay bars, or are sexually active for that matter. He chose, he lost, he is discredited.
