Really? You can prove that gender and age have nothing to do with it? You are perhaps a clinical psychologist who has studied the effects of gender and age on hallucinatory behavior? If so, just tell us where your research results are published. Otherwise, you may find the conclusions of some of those who have studied the subject interesting:

Schizophrenia is a mental illness characterized by episodic positive symptoms such as delusions, hallucinations, paranoia and psychosis and may include persistent negative symptoms such as flattened affect, impaired attention, social withdrawal and cognitive impairment. Epidemiologic and clinical evidence suggests an influence of estrogens on the vulnerability threshold for schizophrenia. Although early studies suggested the incidence of schizophrenia in men and women was about equal, more recent studies indicate incidence rates are higher in men.
It has been suggested that estrogen may act as a protective factor in women; the age of onset of schizophrenia is significantly later in women than in men, with a second peak of onset larger and later in women after 40–45 years of age. As well, levels of psychopathology have been observed to fluctuate with phases of the menstrual cycle. In women with schizophrenia, relapse rates are higher when estrogen levels are low during the menstrual cycle, whereas relapse is low when estrogen levels are high. Higher rates of relapse in women with schizophrenia are also observed during the postpartum period (low estrogens), whereas relapse is low during pregnancy (high estrogens).
Sex differences in the clinical expression of schizophrenia have also been observed. For example, women with schizophrenia have a higher prevalence of auditory hallucinations than men. Women with schizophrenia have been described as “hallucinatory, illusionary,” with symptoms mimicking affective disorders, whereas men tend to become “dull, autistic” and have an amotivational syndrome with loss of organization and regulation.

There is lots more. In fact this is just the tip of a sizable iceberg. And here’s another tip for you: You refute claims with evidence, not with opinions. To claim that gender and age have nothing to do with hallucinatory and delusional behavior in the face of overwhelming clinical evidence to the contrary is simply ignorant. Ignorance in the pursuit of political correctness is no virtue.
