Would you consider them famous just because of an accident of birth? And I was pointing out mistakes in the AOII list. Because...I'm an (wait for it) AOII!
I think they are famous, sure. Fame isn't merit based, no matter how much the Kardashians or Hiltons make me wish it were.
I'd be happy to claim the Bush twins if I were a Theta and even happier about claiming Laura Bush.
