I don't know about bad, but definitely frightening.
Since 'cohabitation' is seen as morally offensive by most heavily (and some moderately) religious, what's to stop a law banning marriage between two people that have been living together for any period of time? Some might say this is a stretch, but in these times, it doesn't seem like that much of a stretch. If something like this was instituted, Brian and I couldn't get married and that would suck.
