See, that's exactly what I'm talking about.
Kemo Sabe up there is getting to the crux of the matter, the grounds for the right to marriage, while Thad's rightly pointing out that on the surface there's a smorgasboard of bullshit that hides or distorts that fundamental truth.
I don't think Slippery Slope applies, because if you have a healthy, intact, loving family where a child has been raised by two gay parents that mirrors the effect on society as a child raised by straight parents. Sure, there are studies that will be trotted out by the right that suppose that a child raised by a gay couple is at some kind of disadvantage as opposed to a straight couple, but how many children have been raised by batty (or friendly) old uncles or aunts? By single parents? By grandparents? By orphanages or foster homes? Yet none of those are unconsitutional.
