Ramesh, I noticed in Comedy Central’s Indecision coverage, Jon Stewart had no doubts. As they replayed lines from Kerry’s speech, the constitution line was one of them. Stewart’s reax went something like: Wait. I don’t get that one. Stage hand walks over, whispers in Stewart’s ear. Stewart looks shocked. Gay people want to do WHAT?!?

I think it’s safe to say that’s how people read it–as an FMA reference.
