Lol, alright so you're a "religious nut" as my friend calls you.
And yes, I do. Unlike you, I believe they are people. Under the constitution all people are equal, and all people deserve the right to liberty, justice, and the pursuit of happiness.
Also, aside from religion and tradition, there really is no reason to let them marry. I mean sure gay love is "gross" but you don't have to watch them now do you?
Also word from aforementioned friend if he were here: Stop inbreeding.
