Dr Neil Whitehead is a member of the discredited group NARTH (National Organization for the Research and Therapy of Homosexuality). No one in the scientific community takes that organization seriously because it pushes "reparative therapy" - the false notion that homosexuality is a condition which can be changed.
He publishes very well debunked 'studies' and has been debunked numerous times by leading sciences. Dr Throckton completely owned him.
