Anyhow. My point being, in all 3 cases, tranny shit is the result of varying severity levels of mental illness.
OCD is very obviously a brain disease which in the current environment is being exploited heavily by plastic surgeons and other such "experts."
Congenital homosexuality (I will explain this concept in a minute) due to political pressures has been removed from diagnostic manuals but still remains an unrecognized mental illness with prenatal onset, much like autism.
Cluster B personality disorders (AKA psychopathy) are not mental illnesses per se, they are statistical extremes of normal behavior in human populations, but their behaviors result in such destruction and dysfunction that they are included among "mental disorders" anyway. They're caused by genetic tendencies towards undersized amygdalas (resulting in aggression, lack of empathy, understimulation, impulsive sensation seeking behavior, and social dominance). The most well known genetic cause of undersized amygdala is the "warrior gene" affecting 9% of the population (and 3x higher in negroids).
