No, the formal definition of marriage used to be one man and one woman, both religiously and civilly. That civil authorities are calling two men or two women married is no more sensical than civil authorities calling an apple an orange. It doesn't change the reality or the substance, it just misapplies the term marriage to same sex couples. Call it what you want, but its still an apple. Sorry you can't comprehend this logic.
Maybe a better question is exactly what additional rights do same sex couples get with their faux marriage over a civil union? The answer is absolutely nothing. What they seek is something that they can never achieve even with this misapplication of the term marriage. They are still making a lifestyle choice that violates natural law and God's law and they know it. It is why they will continue their activism until they can use the full force of government to force those of us with legitimate relgious and natural law objections to same sex "marriage" into silence or worse. I and many others predicted they would not stop with civil unions despite their protests to the contrary. Watch and wait. They are so predictable. And no, life for people suffering same sex attraction is anything but good. And it has nothing to do with the lack of civil unions or marriage or whatever and won't be good if they accomplish the silencing of people with objections to their lifestyle. They seek that which they can never get.
