Wow, now I think I'm even more confused. I figured you were saying it to be funny. So you believe that the institution of marriage is wrong? Can you explain that to me. I've never even thought of that. But I would love to hear what you have to say.
Sure, thing, though I'm mostly used to Australian law so some of what I say may not match up to your experiences.
I think that if a man and a woman fall in love and wish to spend the rest of their life together, possibly raising a family together, then that's fantastic. I also equally believe that if a man and a woman has lustful feelings for one another and wish to spend a night together and never see eachother again that's also fantastic. Along with everything in between. Ditto for man and man, woman and woman, many people of assorted genders, the intersexed, the transgendered and all permutations thereof in all the wonder and variety that nature and technology allow.
If people want to wear rings or invite their families to ritual to announce these intentions then I support their decision. Likewise if they wish to call eachother husband and wife or invite religious leaders to speak at these events. I think this is all just fine.
However... I do not think that any of these should influence taxation, hospital visiting rights, inheritance or any other mechanism of society. I do not believe that divorce procedures or prenuptual agreements should exist. I do not believe that marital status of parents and thus bastadry of children should influence anything (note: Now it does not, however in the middle ages it did).
In Australia, one common complaint of the gay community is that when a man bequeaths superannuation to his wife it has a very low tax rate (it might be zero, I can't remember exactly) whereas should he bequeath it to his boyfriend it has a much higher tax rate.
Situations like this shouldn't exist. The solution, to my mind, is not to allow gay marriage with all the same rights and regulations as straight marriage, but to remove the word marriage from every law. A person's marital status should not matter when they speak to a police officer, judge, lawyer, politician or any other person of authority.
If it matters to them, their family and their friends though, then I think that's fine and fantastic.
