But it's a principle not yet rooted in a legal decision. There is no connection between Loving and gay marriage, other than in discussions or debates. No case that I'm aware of, has a judge referenced Loving as precedent. Things change each time a judge makes a decision based on prior court rulings. Each time they do so they are affirming the original decision to be applicable to the current one. Your desire to link the 2, Loving and gay marriage, is only theory at this point.
