Simcha613 – That is definitely true. Correlation is far from causation. And the argument is exactly what is said by these groups. If they were more accepted then these things would not happen. To be honest, there could be some merit to that. However, some of the health issues are not related to marriage and acceptance. Even in places like San Francisco where it is almost an honor to be gay the rates of many diseases are still way higher and I’m pretty sure the depression and the like are the same. (no study has shown it to be different there).
One more things, the gay lifestyle has been shown to be especially out of control in many ways such as: drugs, pedophilia, and staggering number of people who they have been with (trying to keep it G-rated). Way way way more than heterosexual people. I find it very hard to believe that these things would change if they could marry legally. (in California it has been legal for some time now).
