On last night’s Daily Show, Jon Stewart debated Bill Bennett on gay marriage. (That’s a link to the video.) I always root for Stewart when he debates conservatives on social issues, but I always wind up frothing because he leaves out certain arguments that I would have made, or he misses an opportunity to make a good point about something and instead makes a joke. I always wish I could butt in.
For instance, Bennett brought up the common “slippery slope” argument that gay marriage might lead to polygamy. I LOATHE slippery-slope arguments. Here’s my response: issues should be argued on their own terms. Look – if you can’t think of valid, independent arguments against polygamy, then maybe polygamy should be legal. Oh? What’s that? You argue that I’m being ridiculous, because polygamy is sexist and creates economic inequality among husband and wives? Well, there you go! There’s your argument! Now, how exactly does legal gay marriage invalidate that argument?
For the record, Stewart did point out (although he didn’t say it very well) that homosexuality is part of who a person is, while polygamy is a choice. But I don’t think that’s a valid argument in and of itself. You can’t just argue that polygamy is a choice, because someone could respond, “It’s not a choice that I love all three of these women.” You have to argue about the effects of polygamy, not about the cause of it. It can be fun to watch Jon Stewart debate someone, but it can also be frustrating.
