From the state and federal point of view, marriage is a legally recognized pact carrying with it an entire set of legal obligations and entitlements.
You don't need a church to get married in the eyes of the state, once you sign that piece of paper, you are hitched. From the states' point of view, the ceremony is irrelevant.
Gays are not asking the churches to perform marriages, they are asking the state to recognize them. The issue of "marriage" is I think, being pushed to hard by the gay lobby, and a widespread acceptance of civil unions has to precede the request of Americans to alter their traditional understanding of what marriage is.
You have to examine this issue from a social policy point of view.
Alfonso doesn't like the idea of one man dicking another up the ...
but I don't think most lawmakers are too concerned about this. I am sure there are many hetero couples who engage in sexual practices that disgust people like Alfonso, but I doubt people will make sexual acts the standard by which to allow marriage or not. His example of prison men going gay is pretty silly. Half of those performing gay sex acts are punks, the other half are psychos. I certainly don't want to create laws for civil society based on the behaviors of sociopaths who are doing heavy time in the joint. Does anyone here disagree with me?
There are many children being raised now by same sex couples and as such, certain protections and entitlements afforded families headed by hetero parented families will need to be extended to these families: civil benefits, health benefits extending to families, insurance protection, tax benefits intended for families raising children, social security protections. Gay couples are already raising families, and it is not something we can stop.
To deny same sex couples, even those without children, is punitive and destabilizing. It would be important and frankly good social policy to encourage monogamous and stable pairings of gay people. Doing so will not create more gays, and continuing a system of prejudice will not reduce the amount of gay people. Good social policy dictates recognizing a commitment between gay partners and allowing them to treated by the state and under law as a "married couple".
Monogamous pairings has as a goal social stability, and security garnered from the commitment of one to another. In this case, it may even result in less promiscuity among gay men.
PS. Alfonso, are you telling us that one hot babe chowing down on another is disgusting to you? Personally, I would miss the opening for that scene.
