These “researchers” are confused about what is the cause and what is the effect. For political reasons, they are unable to accept the premise that the population they are describing are dysfunctional and maladaptive, and unsuited to manage their lives as a result. Homelessness is the outcome variable. All the rest is causative, or at least fall in the category of risk factors.
I know of three gay people. Two are males and one female.
The each have good jobs/professions and pass for sane people.
However, they are open about their condition but do not flaunt it. I avoid them because I have a phobia about queers.
