Forcing some people who are legally married, into "Legal Union" feels wrong.
Yes I understand why many people do not see SSM as real marriage, and that's fine. But it is one thing in having that belief and still allowing couples you disagree with to call themselves "married", and one thing to not only disagree with them, but force them to call themselves something else, even if they are legally married. Asking people to be dishonest
The whole "belief its no true marriage, therefore you cant be called married" is similar to forcing people who identify as Christian, as not being allowed to call themselves Christian because they hold a certain belief that other Christians disagree on. Example. What if a Christian hold a non-eternal view of hell, perhaps Universal Reconciliation? Should he be forced to remove the label "Christian" because many Christians disagree with him on this matter? What about evolution and old Earth? I have noticed non-evolutionary Creationism is strong here on this website. Would it be wrong to force evolutionary creationists to not call themselves Christians because some believe evolution goes against the Bible? I think it would be.
What about Christians who don't think the Bible is inerrant/infallible? Should they be forced to remove their Christian tag by people who considered those beliefs as anti-Christian (or even further, that person isn't a real christian)?
Already people who are not following a traditional christian marriage (non-Christians marrying) are allowed to be called married. People who have been divorced to before, and remarried are also allowed to be called married here, even though some would say its not a true marriage. So why is SSM the exception? All what I listed above is apart of Legal Marriage, so why should SSM be singled out?
