I'll betcha they wouldn't let me marry my Strat -- or my sister, or my three closest friends. When people say they don't want the government to define marriage, they don't really mean it. What they mean is that they want the definition expanded to where they want it (which 999 times out of a thousand means to include gays), but not further.
Pretty much!
Though, just for kicks, I'd wander into New Paltz and ask to marry my computer.
Just to see how they respond.
