I kind of agree with the original study for about half the cases.
Hate does cut years off of their life. The study just misidentified which hate it was.
Almost all homosexuals hate themselves. Deep down they know they are sinning and that they are not right. That is why they have this incredibly huge need to be constantly affirmed by society and everyone in it.
Their conscience convicts them on a daily (hourly?) basis and they hate themselves for it.
Eventually the consistent wrong they are living in kills them (leads them to somehow kill themselves)
(The other half of cases dies prematurely from one of the hundreds of diseases that the homosexuals inflict upon themselves)
Impressive.
