If a defense attorney told a judge, "Judge, I swear I saw evidence that proved my client's innocence. He's innocent. Please go look for the evidence because I already talked about it with someone else outside this courtroom..." what do you think would happen? Meaning, if there is a study to show, and it says what you claim it does (I am not saying it doesn't) then by all means - the burden of proof is on you
Despite my sarcasm there, I did some research for you, and found nothing like what you are saying. In fact, there are quite a few studies showing that it is, in fact, societal chastising, rejection and in essence, persecution for their lifestyle. Not because they can't handle the normal relationship problems.
Here are some quotes from WikiPedia, all with sourced references at: http://en.wikipedia.org/wiki/Suicide_among_LGBT_youth
The Family Acceptance Project's research has demonstrated that "parental acceptance, and even neutrality, with regard to a child's sexual orientation" can bring down the attempted suicide rate.
Clinical social worker Caitlin Ryan's Family Acceptance Project (California State University, San Francisco) conducted the first study of the effect of family acceptance and rejection on the health, mental health and well-being of LGBT youth, including suicide, HIV/AIDS and homelessness. Their research shows that LGBT youths "who experience high levels of rejection from their families during adolescence (when compared with those young people who experienced little or no rejection from parents and caregivers) were more than eight times likely to have attempted suicide, more than six times likely to report high levels of depression, more than three times likely to use illegal drugs and more than three times likely to be at high risk for HIV or other STDs" by the time they reach their early 20s.
This higher prevalence of suicidal ideation and overall mental health problems among gay teenagers compared to their heterosexual peers has been attributed to Minority Stress.
Minority stress theory suggests that minority status leads to increased discrimination from the social environment which leads to greater stress and health problems. In the presence of poor emotion regulation skills this can lead to poor mental health. Also, the differential susceptibility hypothesis suggests that for some individuals their physical and mental development is highly dependent on their environment in a “for-better-and-for-worse” fashion. That is, individuals who are highly susceptible will have better than average health in highly supportive environments and significantly worse than average health in hostile, violent environments. This helps us understand racial/ethnic disparities in health conditions as well as the problem of LGBT youth suicide.
In these studies outlined on this page, no mention of religion, religious right, and also no mention of them being less able to handle the situations relationships put forward.
The prosecution rests, Your Honor
