Accepting same-sex marriage won't fix the problem of immoral lifestyles and behaviors. It's hard to solve that kind of problem by govenrment endorsing 'marriage' for them. Individuals who base their central identity on the kind of sex they have will not simply stop sleeping around because the U.S. govenrment recognizes their immoral relationship as marriage any more than cohabitors have solved any social problems by their immoral relationships. Face it, immoral relationships lead to problems not solutions.
