Having said that, Psychiatry is the “Great Satan” of Scientology. As early as 1955, L. Ron Hubbard’s attitude was already well formulated in a bulletin titled Psychiatrists, in which he wrote, “One cannot cooperate with them any more than he can ‘do business with Hitler.’” In 1982 Hubbard claimed that psychiatrists “…destroyed every great civilization to date and are hard at work on this one.” Hubbard’s vilification of psychiatry is a chaotic litany of conspiracy theory paranoia that the Church has adopted as fact. They truly believe, as Hubbard did, that “…the majority of psychiatrists maim and kill their patients and, by record, in all history have only worsened mental conditions. After all, that’s what they seem to be paid to do by the government.”
Tom Cruise (or any Scientologist for that matter), has no choice but to vilify psychiatry. They're forbidden to seek any kind of mental treatment other than their own brand of "spiritual counseling." In fact anyone who has been treated by a psychiatrist or psychologist is potentially ineligible for Scientology processing. At the very least, such a person is required to submit to a "rundown" to undo the supposed harmful effects of conventional mental health treatment.
So when you ask a Scientologist what they would recommend to treat a mental disorder they are bound to one, and only one answer: Scientology.
Are you sure he said 'psychiatrists'? I doubt it, since even Hubbard knew there were no psychiatrists around during earlier civilizations that we know much about.
Hubbard was clearly mentally ill himself. However, in his defense, I'll note that psychiatry in 1955 was still a primitive and scary field. They were still prone to doing bungled frontal lobotomies (like the one on the poor Kennedy girl, who was simply mildly retarded), which often left people virtual vegetables. For Scientology to pretend that 1995 psychiatry and 21st century psychiatry are comparable is absurd (but then, what aspect of their teachings aren't?).
