Yes, individuals that were members of a mixed-race marriage performed in another state were jailed. The state did this because it could. Do you really think that if the state thought it could jail LGBT members married in another state it wouldn't? Many states never formally repelled sodomy laws what makes you think this would be any different.
My point is the arguments presented buy opponents of LGBT marriages and mixed-race marriages are basically religious or I just don't like it.
Positive and negative rights are again are an attempt to say if you prevent me from discriminating against someone I don't like you are taking away one of my rights, Guess what, in your private life have at it BUT when dealing with other members of society, either as a businessman, government, or citizen trying to deny someone else the capability to do something based on how they were born, you have no right to do that in the Unites States of America. Denying marriage because you feel it is wrong for a specific individual to marry negatively impacts them much more than it does you. Many, many laws and judicial decisions in this country grant rights based on marriage status. Eliminate those and we can talk about the rest.
