„People keep asking me, "You mean you don’t believe that HIV causes AIDS?" And I say, "Whether I believe it or not is irrelevant! I have no scientific evidence for it." I might believe in God, and He could have told me in a dream that HIV causes AIDS. But I wouldn’t stand up in front of scientists and say, "I believe HIV causes AIDS because God told me." I’d say, "I have papers here in hand and experiments that have been done that can be demonstrated to others." It’s not what somebody believes, it’s experimental proof that counts. And those guys don’t have that.“
