Here is my take on it… For me personally, I don’t care that what people choose to do with other people, as long as they aren’t infringing on the rights of that other person. So, in that sense, I support “gay marriage”, simply meaning, I don’t deny anyone the right to have that relationship and do what they want with that other person. I don’t condone it, and I think it’s wrong, but I wont deny someone that freedom.
With me the issue is simply a matter of definition. I believe that there is a special relationship that can occur only between a man and a woman. It doesn’t mean I deny someone the right to have that relationship with someone of the same sex, I’m saying I believe that their relationship is simply different. That being said, marriage has traditional been the word used to refer to that special relationship between a man and a woman. In a free world, as long as there are people like me who believe there is a difference between a traditional marriage and those relationships between people of the same sex, they’ll find a way to refer to those relationships differently. If ‘gay marriage’ is ‘legalized’, then people will find a new word to refer to that special relationship between a man and a woman. I can’t force people to exclusively use the word to refer to a relationship between a man and a woman, but that’s sort of beside the point.
The problems arise when it becomes a matter of legalization and benefits and so forth. So.. Get rid of the law, get rid of the problem? I don’t care what people call it, I believe that the relationships are different and I’ll use different words to refer to each. I’m free to do that. And they’re free to call the relationship what they want, too…
So I guess in summary.. I think the relationships are different and I’ll use different words to refer to them. But as far as legaliztion goes.. Well, I’m an anarchist, so, I don’t really care what the government thinks about it. I’m not really sure if that’s on par with you’re guy’s views, but that’s the conclusion I came to, the best I can put it in words at 3:00 am. 
Edit: From my unprofessional observation, a stable family with a single mother and a single father is important for a child’s development, generally, in this culture. I’ve seen it with my own eyes. That doesn’t mean it couldn’t or shouldn’t ever be different… But in most cases, now, in our culture, that’s what the children I see need. It tears my girlfriend apart, the lack of a stable relationship with her mother and the lack of a present father figure, amounting to a stable family with a mother and father figure. And it only makes it worse seeing my family with that. That’s what she feels is right and so that’s what she wants and needs. Could be different for different folks in different cultures, I suppose. But I think ultimately, there is a reason that became tradition. If we abandon the tradition simply because it’s tradition, we may find ourselves re-realizing the reasons it became that way. But I suppose I’d be a hypocrite if I denied someone the right to try it a different way.
