This article surprised me in many ways (in a good way).
One key point that REALLY stuck with me:
"Among self-identified LGBT high school students, 29 percent reported a suicide attempt in the previous twelve months, compared to 6 percent of their peers. Implementation of same-sex marriage laws was associated with a 7 percent reduction in self-reported suicide attempts among high school students, with most of the reduction among those who identified themselves as members of sexual minority groups."First of all, 29%! If you care about life, at all, this should shock you and spur you to some sort of action.
Secondly, a law passed that would not affect them for some time was associated (*note, not a direct causal relationship) with a reduced risk for suicide.
As with everything, nothing is purely black and white; there are many reasons to be for or against certain policies and positions. However, these data are important to understand as realize not everything is so simple, and these 'big' policy decisions do have an impact in unexpected ways.
