Psychiatrists obviously must challenge the solipsistic concept that what is in the mind cannot be questioned. Disorders of consciousness, after all, represent psychiatry's domain; declaring them off-limits would eliminate the field. Many will recall how, in the 1990s, an accusation of parental sex abuse of children was deemed unquestionable by the solipsists of the "recovered memory" craze....The transgendered suffer a disorder of "assumption" like those in other disorders familiar to psychiatrists. With the transgendered, the disordered assumption is that the individual differs from what seems given in nature—namely one's maleness or femaleness. Other kinds of disordered assumptions are held by those who suffer from anorexia and bulimia nervosa, where the assumption that departs from physical reality is the belief by the dangerously thin that they are overweight.
But of course, if we can question transgenderism, we can question homosexuality, and that would just open a huge Pandora's Box.
You can't make social policy based uniquely on feelings.
