Not to play devil's advocate here, but do you really believe that heterosexual marriage, today, involves any if the things that you list? Puhleassse!!!! Over 50% end in divorce with children caught in the crossfire - they may as well be born out of wedlock.
Homosexual marriage is not something that I, personally, can support. But, I'll be damned if I think that my moral purity is sufficient to tell people right from wrong. I do my thing, they can do theirs. I'm over the social issues - we've got bigger fish to fry. Put me on the Libertarian bandwagon.

...mine did. Certainly the marriage vows include “decency, morals and God”. The minister includes that and more as well. So I don’t know WTH you’re talking about.
