Disturbed people are more likely to engage in homosexual activity in a desperate attempt to find something positive to turn around the misery that is their lives. When they discover that homosexuality is but a chimera, suicide is an all too frequent outcome. Homosexuality is a symptom of a disturbed mind.
That's an interesting observation.
I have an openly Gay co worker who, although he's a generally nice fellow, does tend to spend about 85% of his time bitching and moaning about things gone wrong in his life: Finances, relationships, family issues, etcetera.
One day he was on a tear about his financial woes, and I'd finally reached my tolerance limit and politely told him to shut the H*ll up, stating he isn't the only person on the face of the Earth with financial problems. There are times when this guy actually does fit the role of the Gay Drama Queen...and that was one such day.
...So there just may be something to this study, given the fact you rarely hear straight people complain in such a fashion about their lives.
