Suzi, I agree completely. It's horrible to see someone advocate cruelty by wrapping it in the mantle of science.
But I try to remember that it's also a sign of how far we've come in a relatively short time. No reputable professional would dream of saying such a thing now, and "reparative therapy" is not just debunked as ineffective, it too is now recognized as being cruel and abusive; many jurisdictions are now making it illegal.
