I am honored to know dozens of die-hard Star Wars fans who do not fit that description at all ... but have also come across many who fit the stereotype to a "T."
I might also suggest that Lucas has had contact with or information about only the geeks who are star-struck or fantatical enough to have tried to get in contact with him, tried to break into Lucasfilm headquarters, or bothered him or his minions at public appearances. I would not be surprised if he has a skewed vision of Star Wars fans ... though I most certainly fault him for not bothering to find out the truth ... that there are tons of such fans who are wonderful people that can function just fine in society, will indeed have sex with their girlfriends, and don't need to press a button on their stormtrooper costume to have their mother come pick them up.
