Gay Marriage: What's It For?

So Michael Williams asks here. IMO he's basically on target - it's about "we're just as good as you" and wanting to suck up some bennies.

Oh, but they're in Love! Fine - you don't have to be a cynic to ask what that has to do with marriage. Are we now to be permitted to marry anything we love?

If we're going to do it and extend it to same-sex couples, what justification do we have to stop there? If the definition of marriage is just some arbitrary social construct, then why can't it group people more than two at a time? If it needn't be restricted by sex, then why should it respect age, genetic distance or even be limited to pairs? And what about the narcissists - why even require two)? Can gays provide any intellectual or moral justification for limiting marriage only to pairs?

Oh yeah, there's this crap about it being a "civil right". I've never heard any legal justification for that assertion. If the intentions of the legislators or justices is to be given any weight, does anyone really believe that any anti-discrimination legal decisions, laws or amendments were made with the intent of permitting gay marriage?

Enough - this has been addressed here many times. Somehow the fact that I have weighed in on this topic doesn't settle it - imagine that....
