Society at large is mandating the lives of everyone in ways that are much more serious and inhibiting than the inability to get married, so that's moot. Someone else's willingness to perform a religious ceremony on you is not a right. You could make the argument that married people receive benefits that unmarried people do not and that particular unfairness should be done away with, which is a very valid concern, but that was never the point. You stop caring about "rights" and "bigotry" when it no longer affects you or where it is deemed socially acceptable to do so - the single, the polygamous, the incestuous, they can get stuffed.
