As a friend and ally of Szasz, I think his biggest mistake was to join forces with Scientology, though he clearly stated that he was not interested in its creed. His duplicitous critics have smeared him with the association ever since. I think Scientology is silly, but no sillier than other religions. It comes in for ridicule because of its attacks on psychiatry, some of which are not carefully made (e.g., Tom Cruise). Still, Scientologists are subject to nothing as cruel as the treatment of Mormons in the early years of their religion.
