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.
People have been changed, radically - by the grace of God. It doesn't mean the old nature doesn't have to be buried anew daily. We all fall short.
The left plays this all or nothing game no human can live up to: eg - the President wins a war in less than a season, his administration helps take out over 6000 terrorists in the Euopean theater alone, and is doing good work across the globe - but he failed because of ...(insert anything here, the truth doesn't matter, nor does national security the lives of the troops or the welfare of the longsuffering Iraqi people).
IOW, if anyone daring to challenge the left's anti-family agenda falls, they will be strung up by folks like Michael Moore and Larry Flynt.
He can't, but God can. Homosexuality is not a lifestyle, it's not a disease, or something 'hardwired' into a person. It is a choice to follow in sin instead of what God wants, plain and simple
