John McCain thinks that gay couples and 'two-parent families' are opposites

I'm trying not to point out all the shit that McCain is getting wrong these days, since it's like parsing the monologue of the piss-dripper sitting next to you on the bus, but this is pretty Sauron:

STEPHANOPOULOS: So, you’re against gay adoption.

MCCAIN: I am for the values and principles that two parent families represent.

Does he think that gays travel in packs or something? That when we talk about gay adoption, we're talking about some sort of Jungle Book situation, with dozens of gays raising a litter of Maddoxes under a rope swing? Do gays not count as two parents? I'm as confused as ... well, as a 72-year-old man trying to understand the world as it exists since youngsters started rocking their hips on the teletube.
