That's not actually what science says you moron. You can't evoke it only part way and discard the science that hurts your little fee fees.
Science tells us that these mental health issues are caused by ostracization, bullying and violence and not an inherent aspect of being gay. Science also tells us that we can't stop people from being gay but we can mitigate shitty behavior with social and legal incentives and punishments. The correct treatment is intolerance of people who bully gays. That's what the science says.
