Therapy has helped many people. Alcoholics don’t give up alcohol easily either. Addictions and bad habits of the mind and body can be hard to let go of, but his comments mischaracterize the treatment and are not helpful. They are a step toward weakening the SBC position whether persons next to him who like him want to admit it or not.
Put in mind that it often takes multiple times to see significant progress for alcoholics as well. I also agree with the point about mischaracterization. Part of becoming celibate is about developing a decent amount of self-control.
Try quitting smoking.
