Not at all. I'm in a very loving relationship at present that may or may not lead to marriage down the line.
However, that does not preclude me from being realistic about how our culture perceives marriage owing to things like the media, which likes spread the idea that marriage grants a relationship "legitimacy".
This is why I don't agree with equal marriage advocates when they say "it's about love". No, it's not - it's about equality under the law.
