Sorry, but as far as I can see, Quackwatch is the biggest quack in existance.
You will notice that almost none of the listed practitioners are actually doctors and there are many who have been convicted. It is a propaganda site against naturopaths, homeopaths, and alternative practitioners.
Stephen Barrett, M.D. has been sued many times and lost most if not all of those suits.
While you may think that Rife has been debunked, no one who uses one would agree with anything on that site. The Rife machine and other similar devices have a solid scientific foundation and can be very effective. If you are really interested, read "Body Electric" by Dr. Robert O. Becker, M.D. and "Cross Currents" by Dr. Robert O. Becker, M.D.
