Great, I'm glad you know more about psychology than the majority of psychologists in this country. As long as they say what you want to hear than its not political, right? Whatever. I'm done.
If the psychologists say something scientifically demonstrable then they are experts. If they simply say "homosexuality is a normal variant" then they are expressing an opinion of no more value than mine or yours.
There is no body of knowledge that makes anybody any more expert on what is "normal" or "abnormal" than you and I can examine, right here on this thread.
