Found this study from the University of Queensland and Washington University School of Medicine while browsing my university library.

It's shown there is a 60% overlap between the genes that cause homosexuality and higher rates of mental illnesses. It's also found that being homosexually abused as a child increases your chances of being a homosexual. So theoretically if we cracked down on child abuse, and pedophiles abusing little boys we'd see a decrease in the amount of homosexuals.

Zietsch, B. P., Verweij, K. J., Heath, A. C., Madden, P. A., Martin, N. G., Nelson, E. C., & Lynskey, M. T. (2012). Do shared etiological factors contribute to the relationship between sexual orientation and depression?. Psychological medicine, 42(3), 521.

Here's a copy to the full study for those who aren't in school.

Our study replicated previous findings that nonheterosexuals are at elevated risk of depression, an effect that we found in both men and women. To assess the viability of ‘common cause’ explanations of this effect, we initially determined what factors were significantly associated with both non-heterosexuality and depression. Genetic factors accounted for 31% and 44% of the variation in sexual orientation and depression respectively, broadly consistent with the range of estimates from previous studies (Pillard & Bailey, 1998; Kendler et al. 2000, 2001; Sullivan et al. 2000; Levinson, 2006; Santtila et al. 2008; Zietsch et al. 2008; Langstrom et al. 2010). Childhood experiences of sexual abuse and risky family environment were also significantly associated with both sexual orientation and depression. Paternal age, maternal age, and number of older brothers had little effect on either sexual orientation or depression. In men parental physical abuse and number of close friends were significantly associated with depression but not with sexual orientation, whereas non-heterosexual women and depressed women both had higher rates of parental abuse as well as significantly fewer close friends.



We then examined to what extent the factors associated with both sexual orientation and depression explain their association. A significant genetic correlation between sexual orientation and depression indicated an overlap in the genetic factors underlying the two variables. This overlapping genetic etiology accounted for 60% of the covariance between sexual orientation and depression. Further analysis revealed that childhood experiences of sexual abuse and risky family environment accounted for 8.5% and 7.7% of the covariance between sexual orientation and depression respectively, whereas number of close friends accounted for less than 2% of this covariance in women. These results suggest that genetic factors, childhood sexual abuse and risky family environment are all involved in the elevated rate of depression in non-heterosexuals.


It's also shown that child abuse stresses the brain and causes damage to it which causes you to turn into a homosexual and get other mental illnesses. Also those who have non-traditional families, i.e divorces and parents who are criminals are also more likely to homosexual.


In both males and females, adverse childhood experiences elevated the likelihood of non-heterosexuality and also of depression. Many studies have found an association of both childhood abuse and risky family environment with adult depression (Felitti et al. 1998; Nelson et al. 2002; Kendler et al. 2004, 2006; Fergusson et al. 2008). Although the mechanisms involved are not yet entirely clear, there is mounting evidence that these associations are mediated by permanent effects of repeated stressors on hypothalamic–pituitary–adrenal (HPA) axis reactivity (Heim et al. 2008; Pariante & Lightman, 2008; Lupien et al. 2009; Romeo, 2010; Young & Korszun, 2010). In earlier studies, sexual orientation has also been linked with childhood sexual abuse (e.g. Cameron & Cameron, 1995; Paul et al. 2001; Tomeo et al. 2001; Balsam et al. 2005; Arreola et al. 2008; see Rothman et al. 2011 for a review) and, in one study, with family instability (frequent change of parents and parent criminality ; Fergusson et al. 1999).

Very likely.

Still, it bears looking at. Being raised by criminals not only contributes to future criminality, but also homosexuality? That seems suspect.

Gotta love the right wing nut jobs who fund studies that agree with their corrupted and wrong views. Now we're blaming genes and being raped as a kiddie for being non-heterosexual.

I got a newsflash my bi-sexuality was not caused by either.

And what irony is that? Are you assuming I don't think the left does the same? Just cause I criticise one thing doesn't mean I support it's opposite. You lot need to unlearn such fallacy and laziness ya know.

Hey, I wasn't referring to you. I was referring to the fact that the left is guilty of the same thing.

Well I am just really fucking tried of all the right wing nut jobs thinking I am a leftist simply cause I think they're rabid dogs foaming at the mouth. I am a centralist, but I guess I can hardly blame the Americans for thinking otherwise. Their political spectrum leaves a lot to be desired.

Milo younopolis (Idk how to spell that) was molested by a male when he was a child and now he's super gay. He's said that the event scarred him badly. I've heard that story where a young boy who gets raped by a male becomes gay pretty often...

Interesting study OP

Out of curiosity, I poked around a bit on the "Child sexual abuse causes homosexuality" theory. Here's what I found:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3535560/
"men with histories of childhood sexual abuse were significantly more likely than controls to report same-sex sexual partners"

https://www.ncbi.nlm.nih.gov/pubmed/19130206
"In instrumental variable models, history of sexual abuse predicted increased prevalence of same-sex attraction by 2.0 percentage points (95% confidence interval [CI] = 1.4, 2.5), any same-sex partners by 1.4 percentage points (95% CI = 1.0, 1.9), and same-sex identity by 0.7 percentage points (95% CI = 0.4, 0.9). Effects of sexual abuse on men’s sexual orientation were substantially larger than on women’s."

Basically, child sexual abuse contributes to homosexuality, primarily for men. However, caution should be taken when interpreting the causal nature of some results. The second study it seems does a good job of controlling for the possibility that some of the statistics may be skewed by the fact that LGBT children are generally at a higher risk of sexual abuse.

Personally, I'm not all too surprised by this information. Child sexual abuse is a traumatic experience which in many ways can influence your sexual identity and your future relationships.

However, it does not appear that this could be used as a predictor. The second study I posted indicated a 0.7% shift in sexual identity due to child sexual abuse, and the majority of those who possessed a homosexual identity were not victims of childhood sexual abuse.

It seems funny when we accuse academia as a whole of being extremely left biased with studies like these. That being said, it seems like a valid study, and I appreciate you taking the time to format it. I will have to read it tomorrow.
