I entered into a cognitive reverie yesterday and the most delightfully revealing thought experiment entered into my head. It has to do with drawing moral lines. By using the liberal arguments for amorality against a hypothetical proponent of gay "marriage", our proponent ends up hitting a wall.
So here's the thought experiment: a pro-gay "marriage" lad, who happens to be called Bob in my reverie, is taking a walk through a park where he runs into a most intriguing personage named Fred. Their discourse went as follows:
BOB: Hey, Fred!
FRED: Hey Bob, what's up?
BOB: Not much. Hey, are you voting for that gay marriage amendment on Election Day, you know, the one defining marriage as between both heterosexual and homosexual couples? It will finally let people who love each other get 'married' and give them the 'rights' they've so longed for!
FRED: Heck yea, man. Freedom from bigotry. True equality! But I don't think the amendment goes far enough. What if, like, a buncha' people love each other? Like, a buncha' dudes? Why shouldn't they get married? That's not fair.
BOB: Oh, well...Yeah. I guess so. Yeah, maybe they should be allowed to.
FRED: Yeah. You know what used to be 'in' and should come back? That thing where one guy has a bunch of wives. Yeah, polygamy!
BOB: Uh, well... That's a little weird.
FRED: Why's that weird? If they
love each other, why not? I mean, why should only gays get to marry? Are you saying polygamists don't have rights? Are you imposing your morality on me?
BOB: Well no, dude. That's just a little weird, don't you think? I mean, gays should get rights but the polygamy thing is weird.
FRED: Why's it so weird? One man, many women! Why limit people? We're a nation of liberty! Stop pushing your morals on me, dude! I mean, if I love my mom
that much, well, dude, why not?
BOB: You're joking, right? You're talking about in-...
FRED: Yeah man! Nothing is greater than
love! We should be more open and inclusive, and less divisive. Why should
your definition of love be pushed on me?
BOB: Well...No...It shouldn't. But, that's disgusting.
FRED: If I think it's ok, it's ok! Don't tell me it's disgusting you bigot! It's just different!
As we can see, the Pandora's box that Bob initially opened ultimately swallows him whole, as he finds himself in a moral no-man's-land where he can't say why incest is taboo and polygamy is disgusting, etc. He finds that his initial moral judgment has opened a can of worms and that it comes back to haunt him. He learns that his moral judgment is arbitrary and that he can consequently make no real moral judgments.
It seems that the only moral judgment that is not arbitrary with regard to marriage is that most natural one: that marriage is between one man and one woman in a union of love which alone is capable of bearing new life.
Case closed!
