While I generally agree that the government has no business in the affairs of consenting adults, there is a certain connection between society and the government that oversees it. Afterall, governments spring up so that the social order, whether you like that particular system or not, can survive and thrive. Therefore, I would say that the government has a vested interest in defining the basic institution of society, which is marriage. What is marriage? Marriage is not about love. I'll be a hypocrite when I marry, but I know that this was not the original intention of the insitution. It's a myth propogated by Medieval French poets. It's bullshit. Marriage out of love for the other person, until very recent times, has been a rarity, for all levels of society. Marriage has always been about a couple different things: -Politics. -Children. The political angle is simple. Marriage brings two families together. It provides you with In-Laws. It gives you more resources, more manpower, more everything. It increases your chances for survival, and it definitely increases the chances that your offspring will survive and reproduce themselves. This, of course, leads to children. Marriage removes competition for mates within the group. It formalizes sex, and it forces at least two people to care for resulting children. In polygamous societies it's more than two. Formalization of sex also acts as a check on population, since it becomes taboo to engage in sexual activities outside of the marital institution (this, of course, doesn't stop people from doing it completely). As I said, marriage for love is a myth, and a destructive one at that. Why do I think the divorce rate is so high in America? Simple. People think marriage is about love. People think marriage is about love, and because of that they go in with high expectations of the other person. What happens when you go into a relationship with high expectations? You get disappointed. You realize this is not what you bargained for. You want out. Religious taboos aren't important anymore, so it's easy to divorce... Bam. High divorce rate. Miserable children who grow up with single parents, or step parents. Miserable children who turn into miserable, apathetic adults who grew up with the parent they live with bad-mouthing the parents they don't live with on a regular basis. They become cyinical about marriage, about relationships... they meet someone they love, they decide to get married. The cycle begins again. Why am I against gay marriage, or any other formalization of homosexual relationships? Is it because I hate gays? NO. It's because it reinforces the notion that marriage is about love. That is why gay marriage is destructive to the family.
