"Well, it's just wrong"

That's probably the central argument against Same-Sex marriage, and it could very well be a legitimate argument. I don't think it really is, but I don't claim to have all the answers.

I realized that I didn't mind the idea of SSM back when a gay professor of mines was discussing the issue, and I didn't have the guts to tell him that he shouldn't be allowed to be legally married. If I couldn't make the point to his face and make an honest case as to why gays should be disallowed the privileges of marriage, I assumed that my arguments were probably weak - but maybe they weren't.

I only make this post because I wonder how long it'd take before the "Well, it's just wrong" answer stops working for beastialists, pedophiles, incesters, and most notably polygamists. Would it ever? Especially in the latter two cases which potentially involve consenting adults?

My ideas about this issue are so fluid that they might seem and even be contradictory. I'm trying to develop a position on the topic. It really is such an interesting topic with so many different angles that it gets so very confusing.

Maybe, sometimes, we don't always have to take a position that is perfect. Taking a position, that at some level seems contradictory in a theoretical sense might be okay depending on the practical consequences and repurcussions. I don't know. I think a lot of people are too obsessed with having a "unattackable" and "perfect" position on the issue and I can't see how that's possible.
