So who should we believe? A leading scientific journal or a psychopathic religious zealot? I use the word 'psychopathic' in its nicest sense: apparently oblivious to the consequences of his actions, although I'm by no means certain I believe that. As was pointed out earlier, John Paul II came out with similarly dangerous drivel and was proved horribly wrong. Benedict has repeated the mistake from which he had ample opportunity to learn. Much as I detest the idea of censorship, such people should not be given a public platform from which to air their irrational prejudices and ideals. In a civilised world, religions should never be allowed to dabble in either medical or political matters.
