“Ex-gay” therapist Dr. Jerry Mungadze determines a person's sexuality reading crayon drawings.

In an appearance last week on Daystar's Joni Table Talk, Mungadze, originally from Zimbabwe, claimed that his technique for altering a person from gay to straight, which he calls Right Brain Therapy, literally changes the brain's structure.

“The good news is, at least with the people that I've seen, not a lot of people, when the healing takes place those areas of the brain that were showing the homosexuality show heterosexuality,” he said on the show. “I have had several people who when I looked at them I couldn't tell the difference between a heterosexual who never was homosexual and them, which means the brain is able to go back and fire the way it is supposed to be, which is an argument against the whole idea of someone was born that way.”

Warren Throckmorton reported that Mungadze's approach was to allow patients to draw with crayons.

“Apparently, pink related to femininity, red to anger/aggression, and so on,” Throckmorton wrote. “He says he can tell gay people apart from straights; and when they revert to heterosexuality, he can tell by how they color between the lines.”

“Who needs brain scans when you have crayons?” he added.
