Should a black dog wear a white dress?

If you allow this, then you will not be able to disallow it and it will lead to that which will inevitably lead to that and then that. Got it?

Therefore if we allow women to vote, we'll soon have to allow inferior races to vote and then who is to say we won't have to allow dogs to vote and then chickens and down all the phylae to protozoa. Imagine having to design a voting machine for an amoeba? Those stupid Liberals!!

In a Slippery Slope Argumant, a sequence of increasingly unacceptable consequences is offered as stepping stones to hell. You'll find it listed under Fallacies of Distraction and you'll find it on the tongues of Fox opinionators like Bill O'Reilly and without the slightest embarrassment, it seems.

So of course allowing (as though you had the right to disallow it) people of the same sex to enter into a marriage contract will absolutely and inevitably lead to people demanding to marry earthworms. It's a testament to American stupidity that anyone would fail to see this as an unfounded assertion, but then, the foundation of American Stupidity Culture and Fox News' prosperity, is this very inability.

Of course, just as Zeno can be invoked to prove we can't get there from here, the Slippery Slope can be invoked with similar illogic to prove we will all go to hell without guidance from traditional things like Bigotry and Bill O'Reilly.

The fool asks why, if human beings can enter into a contract without prejudice as to their gender, why not animals? The wise man simply tells him he's an idiot because animals are not human beings, cannot enter into any contracts at all, and the constitution guarantees equal protection under the law only to humans in the first place. The fool doesn't understand and turns to Fox and the Churches who make him feel better by telling him God loves fools and all those other people are heretics and Liberals.

Bill is there to tell the bottom third that if we allow gay marriage, you'd better buy a white dress for your parakeet and they would rather believe that then to believe they're ignorant idiots a parakeet wouldn't want to marry in the first place. I'm tempted to think that in some cases, it might actually help the gene pool.
