People need to think of divorce from a true libertarian perspective. One of the basic tenets of freedom is that no one has the right to live off another. That means no alimony, no child support etc. Because the gov can put a gun to another person's head and make them pay for someone else, divorce is BIG BUSINESS and there's no incentive for many people to stay in it, women especially, when they can use the legal system to rob their partner. Funny, I have never seen a woman ordered to still cook, clean, and sexually satisfy a man in court...the life he was accustomed to so why is it just financial? We easily recognize the latter as slavery, but somehow not the former.
Gov has no business in marriage. If people want to be together, they had better make sure it's right, make sure to work at it, or make sure that they are still a self-sufficient individual which is a good idea anyway as people don't live forever and sometimes die young so having a back up plan is just common sense, instead of the moral hazard gov sanctioned marriage creates.
Oh, was this supposed to be about gays? Doesn't harm me in any way so why should I care? If you don't get that, you're not a libertarian.
