Basically, the Jedi regard all non-Jedi or Sith as "Muggles". Seriously though, especially Obi-Wan's attitude in TPM ("another pathetic life form" ) as well as Windu's, do come across as slightly arrogant. Even Yoda himself makes that observation. So there must be something to it. Not Anakin though, he seems to me as one of the least arrogant Jedi, more down-to-earth - maybe because he is critical towards them from the beginning and less indoctrinated?
